Power supply currents of CMOS digital circuits partly flow through a silicon substrate in their returning (ground) paths. The voltage bounce due to the substrate currents is seen wherever p+ substrate taps on a p-type die and regarded as a substrate noise. An on-chip waveform monitor confirms the side-channel leakage on the silicon substrate from an AES cryptographic module in a 65 nm CMOS demonstrator...
In this paper, we consider Doppler compensation for time varying underwater acoustic channels. The underlying system model comprises two sources, S1 and S2, communicating with each other through a relay, R. The transmission process goes through two phases. In the first phase, the two sources transmit simultaneously and the relay receives. In the second phase, the relay processes the received signals...

Speech processing is now an emerging technology of signal processing. Some research areas of speech processing are recognition of speech, speaker identification (SI), speech synthesis etc. Speaker identification is important research area of speech processing. SI means identifying the speaker based on his spoken speech. The main use of SI is to recognize the speech owner based on the speaking style...
Psychoacoustic studies show that the strength of masking is, among others, dependent on the tonality of the masker: the effect of noise maskers is stronger than that of tone maskers. Recently, a Partial Spectral Flatness Measure (PSFM) was introduced for tonality estimation in a psychoacoustic model for perceptual audio coding. The model consists of an Infinite Impulse Response (IIR) filterbank which...

We further expand the structure to a 3×3 TSV array and investigate...
An effective method s proposed to enhance the SI and PI of a power-bus structure PBS) in a layered medium PCB by suppressing the EMI-causing resonance mode It s implemented by a complementary split-ring-resonator as a 1-cel metamaterial-inspired geometry formed in the PBS to remove the resonance that hinders the signal transfer from one layer to another. The method is verified by the full-wave simulation...
Machine Learning (ML) is a well-studied strategy in modeling Physical Unclonable Functions (PUFs) but reaches its limits while applied on instances of high complexity. To address this issue, side-channel attacks have recently been combined with modeling techniques to make attacks more efficient [25][26]. In this work, we present an overview and survey of these so-called “hybrid modeling and side-channel...
In this paper we provide an overview regarding the feasibility of in-band full-duplex transceivers under imperfect RF components. We utilize results and findings from the recent research on full-duplex communications, while introducing also transmitter-induced thermal noise into the analysis. This means that the model of the RF impairments used in this paper is the most comprehensive thus far. By...

The circuit composed of a low-noise instrumentation preamplifier followed by a single bit fourth order...
In this paper, we present a novel real-time velocity estimation algorithm. A sensor assembly consisting of a monocular camera and an inertial measurement unit with three-axis accelerotmeter and gyroscope is considered. To improve the robustness of the velocity estimator with respective to image noise, we apply a coarse-to-fine structure based on multiple feature correspondences over three consecutive...
Triangular In0.53Ga0.47As-OI nMOSFETs with smooth (111)B side surfaces on Si have been successfully fabricated. Triangular shaped channels with bottom width down to 30 nm were formed by MOVPE growth on narrow InGaAs-OI fins. The formed (111)B surface was demonstrated to provide higher mobility compared with reference InGaAs-OI tri-gate (1.9×) as well as bulk (100) InGaAs nMOSFETs (1.6×), which is...
In this paper we propose Pixel-based Random Parameter Filtering (P-RPF) for efficiently denoising images generated from complex illuminations with a high sample count. We design various operations of our method to have time complexity that is independent from the number of samples per pixel. We compute feature weights by measuring the functional relationships between MC inputs and output in a sample...
Recently, full-duplex (FD) communications with simultaneous transmission and reception on the same channel has been proposed. The FD receiver, however, suffers from inevitable self-interference (SI) from the much more powerful transmit signal. Analogue radio-frequency (RF) and baseband, as well as digital baseband, cancellation techniques have been proposed for suppressing the SI, but so far most...

This paper presents the design and performance of a new readout system for gaseous and silicon detectors built for the Minos nuclear physics experiment. A major constraint was to provide a multi-thousand channel, high performance readout system with low manpower effort and tight cost.

In this work, we present the design and the results of the analog channel of the readout circuit for the outer layers of SuperB Silicon Vertex Tracker (SVT). In these layers, the strip detectors have a very high stray capacitance and high series resistance. Therefore, the noise optimization was the first priority design concern. To fulfill the noise level and efficiency requirements, a compromise...
