Brain-computer interfaces (BCIs) could manipulate devices through non-invasive electroencephalogram (EEG) signal. A compact deep convolutional neural network model, EEGNet, and its hardware implementation, has been developed for obtaining generalization towards different BCI paradigms. However, the exist design consumes huge amount of area power resources. are used dynamically on portable in most scenario, which restricted limitations resource consumption. Hence, this paper, we present an...
An all-digital background calibration technique for gain, timing, and bandwidth mismatches in the time-interleaved analog-to-digital converter (TI-ADC) is presented this brief. The proposed employs an interpolation filter a Hilbert to generate reference sequence each sub-ADC. Subsequently, adaptive filters are used calibrate mismatch errors, coefficients of which updated by least mean square (LMS) algorithm. advantage that it only requires output TI-ADC without any additional information or...
This paper presents a coarse-fine bypass window technique to improve the energy efficiency of successive approximation register (SAR) analog-to-digital converter (ADC) by skipping unnecessary conversion cycles when input signal is within windows. It utilizes time information MSB comparison coarsely detect range without dedicated timing budget. Based on coarse detection results, fine configured reusing digital-to-analog (DAC) accurately signal. Due presence detection, multi-window and its...
This work proposes a digital calibration technique for time-interleaved analog-to-digital converters with any interleaving factor, which can calibrate gain, timing, and bandwidth mismatches. A simulated annealing algorithm is used to search the optimum coefficients error correction module, possessing customizable range precision. Furthermore, effective single-tone, multi-tone input signals in whole Nyquist frequency. In case of an 8-channel 12-bit TI-ADC fixed mismatches, simulations show...
Abstract This paper presents an AOT-controlled (adaptive-on-time, AOT) valley-current-mode buck converter for portable application. The with synchronous rectifier not only uses control but also possesses hybrid-mode functions at the same time. Due to presence of zero-current detection circuit, can switch freely between two operating modes without need external mode selection which further reduces design difficulty and chip area. application high power efficiency wide current range is used...
Rice blast caused by Magnaporthe oryzae is one of the most destructive fungal diseases rice worldwide. Stimulatory effects low doses fungicides on pathogens are closely relevant to disease management. In present study, in potato dextrose agar (PDA) amended with carbendazim at a dose range from 0.003 0.3 μg/mL, stimulatory mycelial growth three isolates sensitive were tested. Carbendazim concentrations 0.1 µg/mL showed Guy11 and H08-1a, while 0.03 stimulated isolate P131. The maximum...
The structural, mechanical, anisotropic, electronic, and thermal properties of t-Si₃N₄, t-Si₂GeN₄, t-SiGe₂N₄, t-Ge₃N₄ in the tetragonal phase are systematically investigated present work. mechanical stability is proved by elastic constants t-Ge₃N₄. Moreover, they all demonstrate brittleness, because B/G < 1.75, v 0.26. anisotropy characterized Poisson's ratio, Young's modulus, percentage for bulk modulus AB, shear AG, universal anisotropic index AU. electronic structures wide band gap...

This work presents an parallel analog-to-digital converter based on compressive sensing theory to process compressive/sparse signal below Nyquist Sampling Rate. Linear feedback shift registers (LFSR) are adopted generate a 0/1 pseudo random sequence and first-order delta-sigma ADC is presented computes the inner product of signals in our design. Besides, sampling achieved by using switched-capacitor techniques, therefore cut-off switches regulates selection sequence. The system simulation...
This paper presents a new capacitor array architecture to achieve 6 bit 550Ms/s energy-efficient SAR with 65nm CMOS, which also takes up smaller area than traditional SAR. The bypass logic is key feature speed the SA algorithm. Dynamic used in critical path accelerate speed. whole circuit supplied 1.2V voltage.
