This paper presents the integration and channel characterization of a highly integrated dual-band digital beamforming space-borne synthetic aperture radar (SAR) receiver. The proposed SAR sensor is a low-cost, lightweight, low-power consumption, and dual-band (X/Ka) dual-polarized module ready for the next-generation space-borne SAR missions. In previous works, by the authors, the design and experimental characterization of each sub-system was already presented and discussed. This work expands upon the previous characterization by providing an exhaustive experimental assessment of the fully integrated system. As it will be shown, the proposed tests were used to validate all the instrument channels in a set-up where the SAR sensor was illuminated by an external source minim the ground reflected waves. Test results demonstrate how the system channels are properly operating allowing the reception of the input signals and their processing in the digital domain. The possibility to easily implement a calibration procedure has also been validated to equalize, in the digital domain, the unavoidable amplitude differences between the different channels.

Pattern recognition techniques of myoelectric signals have been widely used to identify hand motions and gestures. These techniques have demonstrated that significant motor control information can be extracted and have been implemented in robotic-assistance like prosthesis control. Nevertheless, few investigations have been carried on subjects after a stroke event. In this study, a series of pattern recognition parameters were investigated in the classification of 4 hand exercises (open-close hand, flexion-extension wrist, spread fingers, and pinch grip) involving the affected limb of 4 stroke subjects. Features from EMG data in the time and frequency domains are extracted for training three different classification methods (svm, knn, lda). The classifiers are trained for each exercise individually. Also, it compares 3 methods of feature selection to maintain high levels of classification accuracy: Two-sample T-test with feature variances, Separability Index, and Davies-Boulding Index. The knn classifier obtained the best performance in average for all cases with 87:4% of accuracy, followed by SVM with 82:2% and LDA with 74:5%. The average classifier performances for each exercise were 90:9%, 84:6%, 83:5%, 66:2% for open-close hand, flexion-extension wrist, spread fingers, and pinch grip respectively.

Microelectronics Reliability 114, 113799 (2020)
DOI: 10.1016/j.microrel.2020.113799, (RESCUE)
This work introduces an embedded approach for the prediction of Solar Particle Events (SPEs) in space applications by combining the real-time Soft Error Rate (SER) measurement with SRAM-based detector and the offline trained machine learning model. The proposed approach is intended for the self-adaptive fault-tolerant multiprocessing systems employed in space applications. With respect to the state-of-the-art, our solution allows for predicting the SER 1 h in advance and fine-grained hourly tracking of SER variations during SPEs as well as under normal conditions. Therefore, the target system can activate the appropriate mechanisms for radiation hardening before the onset of high radiation levels. Based on the comparison of five different machine learning algorithms trained with the public space flux database, the preliminary results indicate that the best prediction accuracy is achieved with the recurrent neural network (RNN) with long short-term memory (LSTM).

(11) Full Error Detection and Correction Method Applied on Pipelined Structure Using Two Approaches

Journal of Circuits, Systems, and Computers (JCSC) 29(13), 2050218 (2020)
DOI: 10.1142/S0218126620502187
In this paper, two approaches are evaluated using the Full Error Detection and Correction(FEDC) method for a pipelined structure. The approaches are referred to as Full Duplication with Comparison (FDC) and Concurrent Checking with Parity Prediction (CCPP). Aforementioned approaches are focused on the borderline cases of FEDC method which implement Error Detection Circuit (EDC) in two manners for the purpose of protection of combinational logic to address the soft errors of unspeci¯ed duration. The FDC approach implements a full duplication of the combinational circuit, as the most complex and expensive implementation of the FEDC method, and the CCPP approach implements only the parity prediction bit, being the simplest and cheapest technique, for soft error detection. Both approaches are capable of detecting soft errors in the combinational logic, with single faults being injected into the design. On the one hand, the FDC approach managed to detect and correct all injected faults while the CCPP approach could not detect multiple faults created at the output of combinational circuit. On the other hand, the FDC approach leads to higher power consumption and area increase compared to the CCPP approach.

This work presents fully-integrated modular wideband frequency interleaving (FI) transmitter and receiver for high data rate communication applications. At the transmitter side three independent I/Q baseband channels are up-converted to different intermediate frequencies (IF) and then interleaved. At the receiver side the interleaved signals are down-converted and separated back to each independent channel. Single-ended inputs and outputs are utilized in order to reduce the pin count, for a more practical realization and higher potential toward future system scaling. Special design techniques are followed to minimize cross-talk and inter-modulation products between the channels. All circuits are manufactured and measured in a 130nm SiGe:C BiCMOS technology with fT / fmax = 300 / 500 GHz. The FI transmitter achieves a channel bandwidth of 2.5 GHz with less than 3 dB difference across the different channels till 15 GHz IF. It consumes 560mW from 2.5V and 3.3V supplies, and occupies a silicon area of 1.9mm2. The FI receiver achieves a baseband channel bandwidth of 2.5GHz with a 1 dB difference between the channels till the same IF. It consumes 890mW from 2.5V and 3.3V supplies, and has a chip area of 1.55mm2. The circuits are deployed in a communication experiment, firstly in a back-to-back test with direct cable connection, demonstrating a data rate of 15.6 Gb/s across the three IQ channels with a 16- QAM modulation scheme and worst case transmitter-to-receiver (Tx-to-Rx) error vector magnitude (EVM) of -18.6 dB. Then a wireless experiment is performed with a 240 GHz front-end with on-chip antenna, demonstrating a data rate of 7.8 Gb/s with QPSK modulation and worst case EVM of -8.3 dB across a wireless link of 15 cm. To the best of the authors’ knowledge this is the first work that demonstrates a wireless transmission at sub-THz carrier frequencies utilizing frequency interleaving architectures.

Thermal Magnetic Resonance (ThermalMR) leverages radio frequency (RF) induced heating to examine the role of temperature in biological systems and disease. To advance RF heating with multi-channel RF antenna arrays and overcome the shortcomings of current RF signal sources, this work reports on a 32-channel modular signal generator (SGPLL). The SGPLL was designed around phase-locked loop (PLL) chips and a field-programmable gate array chip. To examine the system properties, switching/settling times, accuracy of RF power level and phase shifting were characterized. Electric field manipulation was successfully demonstrated in deionized water. RF heating was conducted in a phantom setup using self-grounded bow-tie RF antennae driven by the SGPLL. Commercial signal generators limited to a lower number of RF channels were used for comparison. RF heating was evaluated with numerical temperature simulations and experimentally validated with MR thermometry. Numerical temperature simulations and heating experiments controlled by the SGPLL revealed the same RF interference patterns. Upon RF heating similar temperature changes across the phantom were observed for the SGPLL and for the commercial devices. To conclude, this work presents the first 32-channel modular signal source for RF heating. The large number of coherent RF channels, wide frequency range and accurate phase shift provided by the SGPLL form a technological basis for ThermalMR controlled hyperthermia anti-cancer treatment.

Due to the nature of applications such as critical infrastructure and the Internet of Things etc. side channel analysis attacks are becoming a serious threat. Side channel analysis attacks take advantage from the fact that the behaviour of crypto implementations can be observed and provides hints that simplify revealing keys. A new type of SCA is the so called horizontal differential SCA. In this paper we investigate two different approaches to increase the inherent resistance of our hardware accelerator for the kP operation. The first approach aims at reducing the impact of the addressing in our design by realizing a regular schedule of the addressing. In the second approach, we investigated how the formula used to implement the multiplication of GF(2n)-elements influences the results of horizontal DPA attacks against a Montgomery kP-implementation. We implemented 5 designs with different partial multipliers, i.e. based on different multiplication formulae. We used two different technologies, i.e. a 130 and a 250 nm technology, to simulate power traces for our analysis. We show that the implemented multiplication formula influences the success of horizontal attacks significantly. The combination of these two approaches leads to the most resistant design. For the 250 nm technology only 2 key candidates could be revealed with a correctness of about 70% which is a huge improvement given the fact that for the original design 7 key candidates achieved a correctness of more than 90%. For our 130 nm technology no key candidate was revealed with a correctness of more than 60%.

Modern communication systems rely heavily on cryptography to ensure authenticity, confidentiality and integrity of exchanged messages. Elliptic Curve Cryptography (ECC) is one of the common used standard methods for encrypting and signing messages. In this paper we present our implementation of a design supporting four different NIST Elliptic Curves. The design supports two B-curves (B-233, B-283) and two P-curves (P-224, P-256). The implemented designs are sharing the following hardware components bus, multiplier, alu and registers. By implementing the 4 curves in a single design and reusing some resources we reduced the area by 14% compared to a design without resource sharing. Compared to a pure software solution running on an Arm Cortex A9 operating at 1GHz, our design ported to a FPGA is 1.2 to 6 times faster.

DOI: 10.1016/j.ijepes.2019.105635, (SmartGrid Plattform)
Though extensive, the literature on electrical load forecasting lacks reports on studies focused on existing residential micro-neighbourhoods comprising small numbers of single-family houses equipped with solar panels. This paper provides a full description of an ANN-based model designed to predict short-term high-resolution (15-minute intervals) micro-scale residential net load profiles. Since it seems especially relevant due to the specificity of local autocorrelations in load signal, in this paper we put stress on the systematic approach to feature selection in the context of lagged signal. We performed a case study of a real micro-neighbourhood comprising only 75 single-family houses. The obtained average prediction error was equivalent to 5.4 per cent of the maximal measured net load. Both issues, i.e.: 1) the feasibility of micro-scale residential load forecasting taking into account renewable energy penetration, and 2) the feature selection problem, could be of interest to engineers designing energy balancing systems for local smart grids.

As VLSI design moves into ultra-deep-submicron technologies, timing margins added to the clock period are mandatory, to ensure correct circuit behavior under worst-case conditions. Timing resilient architectures emerged as a promising solution to alleviate these worst-case timing margins. Blade is an asynchronous timing resilient template that leverages the advantages of both asynchronous and timing resilient techniques. However, Blade still presents challenges regarding its testability, which hinders its commercial or large-scale application. This paper demonstrates that scan chains can be prohibitive for Blade due to their high silicon costs, which can reach more than 100%. Then, it proposes an alternative test approach that allows concurrent testing, stuck-at, and delay testing. The test approach is based on the reuse of the Blade features to provide testability, with silicon area overheads between 4% and 7%. Also, the proposed test methodology demonstrated that Blade could be tested in different phases, such as manufacturing, for stuck-at and delay faults, with adequate fault coverage between 70% and 100%.

Millimeter wave (mmWave) communication has emerged as a key technology for achieving high data-rates and low latency in 5G networks. Radio-frequency (RF) or analog beamforming is used to provide additional (beamforming) gain to compensate for propagation phenomena in the mmWave spectrum. In this letter, we analyzed the effects of residual transceiver impairments on the performance of a single-user mmWave RF beamforming system. We derived the closed-form expressions of the ergodic capacity in both Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) channels. The derived formulas are applicable for both perfect and codebook-based beam alignment. In the former, they are exact, while in the latter are approximate, but with a high degree of accuracy. The theoretical findings are verified by Monte-Carlo simulations showing an excellent agreement.

We investigate photocurrents driven by femtosecond laser excitation of a (sub)-nanometer tunnel junction in an ultrahigh vacuum low-temperature scanning tunneling microscope (STM). The optically driven charge transfer is revealed by tip retraction curves showing a current contribution for exceptionally large tip-sample distances, evidencing a strongly reduced effective barrier height for photoexcited electrons at higher energies. Our measurements demonstrate that the magnitude of the photo-induced electron transport can be controlled by the laser power as well as the applied bias voltage. In contrast, the decay constant of the photocurrent is only weakly affected by these parameters. Stable STM operation with photoelectrons is demonstrated by acquiring constant current topographies. An effective non-equilibrium electron distribution as a consequence of multiphoton absorption is deduced by the analysis of the photocurrent using a one-dimensional potential barrier model.

DOI: 10.1016/j.sse.2019.107746
The physically meaningful Boltzmann-Arrhenius-Zhurkov (BAZ) model has been applied to predict the integrated circuit reliability. The model has been modified taking into account the impact of physical defects and process variations (and, consequently, integrated circuit yield) on the stress-free failure activation energy. The probability of non-failure (reliability) and corresponding mean-time-to-failure (MTTF) can be estimated from the failure-oriented-accelerated-testing (FOAT) geared by the modified BAZ model. The concept has been elaborated and illustrated on an application example.
