A two-channel Sallen-Key low-pass filter on three non-inverting amplifiers is studied, which has the property of unrelated digital set of the upper cut-off frequency at constant index of the transmission coefficient in the bandwidth range. The restructuring of the upper cutoff frequency and the attenuation of the pole is carried out by modify the resistors' resistance of one in the upper channel of the low-pass filter. It is shown that a non-inverting amplifier in the lower channel of the low-pass filter can have a small value of the systematic zero bias voltage component, what is important for the operation of the low-pass filter at the input of analog-to-digital converters. It has been established that due to the construction of a low-pass filter according to a two-channel architecture, the requirement for the magnitude of the output static voltage of the upper channel is removed. The base equations of the new low-pass filter scheme are given and the summary modeling in the Micro-Cap was pictured. © 2022 IEEE.

Visible light communication (VLC) technology based on GaN light emitting diode (LED) has been widely studied because of its wide bandwidth and high reliability. However, low integration is one of the main factors limiting the development of VLC technology at present. This study reports a novel GaN-based light emitting diode-high electron mobility transistor (LED-HEMT) monolithically integrated device. The light efficiency is improved not only by adding InGaN quantum well layer at the AlGaN/GaN interface, but also thin Ni/Au layer is used as a substitute for the traditional indium tin oxide (ITO) layer to realize the current expansion function, so that the device has faster switching speed and reliable light modulation ability. The influence of gate-source voltage (VGS) and applied drain voltage (VDD) on the control capability of LED-HEMT was studied. The integrated LED-HEMT exhibited output current can reach 309 mA/mm when the HEMT was modulated with VDD = 14 V and VGS = 2 V, which driving capability is better to previous Si-based MOSFETs, demonstrating good output performance. The peak of the emission spectrum is at 445 nm when IDS = 15 mA. This work offers a novel approach to the monolithic integration of LED-HEMT and provides reference for the application of Micro-LED in the fields of visible light communication and optoelectronic detection. ©2024 IEEE.

Deep learning has evolved as a discipline that has demonstrated its capacity and usefulness in tackling complicated learning issues as a result of recent improvements in digital technology and the availability of authentic data. Convolutional neural networks (CNNs) in particular have demonstrated their usefulness in image processing and computer vision applications. They do, however, need heavy CPU operations and memory bandwidth, which prevents general-purpose CPUs from attaining desirable performance levels. To boost CNN throughput, hardware accelerators such as application-specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), and graphics processing units (GPUs) have been deployed. FPGAs, in particular, have lately been used to accelerate the development of deep learning networks due to their ability to optimize parallelism and power efficiency. Based on hardware-software architecture, this research provides a CNN acceleration model for video compression applications. Vivado High Level Synthesis is used to accelerate the CNN model in order to develop Intellectual Property (IP) cores. © 2022 IEEE.

The paper describes the energy consumption from the battery based on the current measurements for various cases, i.e., speed (PWL adjustment) and loads. The main purpose of the research is to have additional and reliable information about power consumption and battery life estimation for autonomous guided vehicles (AGV). The authors propose a two-step algorithm. In the first step, a linear classifier was proposed. Then, the KNN classifier was tested;however, it did not give satisfactory results, so it was finally decided to use the random forest to estimate the load and PWL. The time domain current measurement is evaluated, and the beforementioned algorithms process the selected statistical measures. It has been proven that a two-step algorithm allows for achieving high accuracy. Based on the current observation, the paper is a good starting point for further investigation of the AGV because it is usually implemented in the AGV - so it does not require additional hardware. Moreover, it can lead to better energy management and increase battery lifetime. © 2023 IEEE.

A new RLC high-pass filter circuit is considered, in which, due to the introduction of additional buffer amplifiers (voltage followers) and resistive voltage dividers, independent tuning of the pole Q-factor and the pole frequency by various resistance is realized at constant capacitance values of the frequency-setting capacitor and frequency-setting inductance. The article discusses the conclusion of modeling RLC high-pass filter in the Micro-Cap, which confirm its claimed properties. The basic mathematical equations for the transfer function of the RLC high-pass filter and the parameters of its frequency response are obtained. The equations obtained above make it possible to develop an algorithm for independent adjustment of the parameters of the proposed RLC filter. The RLC high-pass filter circuitry proposed by the authors is recommended for adaptive filtering of signals in radio engineering and measuring systems. Due to the appropriate parameters choice of passive and active circuit elements, it is possible to ensure the operation of the considered RLC high-pass filter both at low and at high frequencies. © 2022 IEEE.

Phased arrays in near-field communication allow the transmitter to focus wireless signals in a small region around the receiver. Proper focusing is achieved by carefully tuning the phase shifts and the polarization of the signals transmitted from the phased array. In this paper, we study the impact of polarization on near-field focusing and investigate the use of dynamic polar-ization control (DPC) phased arrays in this context. Our studies indicate that the optimal polarization configuration for near-field focusing varies spatially across the antenna array. Such a spatial variation motivates the need for DPC phased arrays which allow independent polarization control across different antennas. We show using simulations that DPC phased arrays in the near-field achieve a higher received signal-to-noise ratio than conventional switched- or dual-polarization phased arrays.

Fast millimeter wave (mmWave) channel estimation techniques based on compressed sensing (CS) suffer from low signal-to-noise ratio (SNR) in the channel measurements, due to the use of wide beams. To address this problem, we develop an in-sector CS-based mmWave channel estimation technique that focuses energy on a sector in the angle domain. Specifically, we construct a new class of structured CS matrices to estimate the channel within the sector of interest. To this end, we first determine an optimal sampling pattern when the number of measurements is equal to the sector dimension and then use its subsampled version in the sub-Nyquist regime. Our approach results in low aliasing artifacts in the sector of interest and better channel estimates than benchmark algorithms. Copyright © 2022, The Authors. All rights reserved.

The modern space industry requires autonomous and high-precision control systems for scientific and commercial missions. Strapdown inertial navigation systems based on laser gyroscopes play a key role in spacecraft control, especially in environments where satellite navigation is unavailable. In this paper, ring lasers with an active medium made of a helium-neon mixture, their design and operating modes are investigated. The influence of voltage on the ignition electrodes (4.2-5 kV) on the breakdown time of the active medium has been analyzed. It was found that increasing the voltage reduces the breakdown time, providing reliable activation of gyroscopes. The experimental results allowed to determine the optimal ignition parameters that increase operation reliability and reduce production losses. This contributes to the development of highly efficient spacecraft control systems, opening up new prospects for deep space exploration and control of satellite systems.
