Wide-Bandwidth CFOA with High CMRR Performance [PDF]
, 2013 In this paper the authors analyze the conventional current-feedback operational amplifier (CFOA) in terms of common-mode-rejection ratio (CMRR) performance, and having identified the mechanism primarily responsible for the CMRR, they propose two new ...

Very‐low frequency capacitively coupled AC amplifier with a current feedback operational amplifier
International Journal of Circuit Theory and Applications, Volume 51, Issue 9, Page 4015-4028, September 2023., 2023 In this paper, we propose the design of capacitively coupled AC amplifiers with transimpedance amplifiers instead of voltage op‐amps or OTAs. The idea is exemplified and demonstrated in practice with a current feedback operational amplifier. Summary In this paper, we propose the idea of using transimpedance amplifiers, in lieu of operational amplifiers

New full‐wave rectifier based on modified voltage differencing transconductance amplifier
IET Circuits, Devices &Systems, Volume 16, Issue 4, Page 322-336, July 2022., 2022 Abstract A full‐wave rectifier based on a modified voltage differencing transconductance amplifier‐MVDTA and four n‐MOS transistors (or inverting full‐wave rectifier), with no use of any passive elements is proposed in this paper. The proposed design is suitable for a low voltage and high frequency input voltage/current signal. The used MVDTA possesses

Bearing Early Fault Diagnosis Based on an Improved Multiscale Permutation Entropy and SVM
Shock and Vibration, Volume 2022, Issue 1, 2022., 2022 Bearing fault is a process of gradual development and deepening. In the early stage of the fault, if it can be found out in time and taken reasonable prevention and elimination measures, we can avoid serious losses and safety accidents. Therefore, the feature extraction and analysis of early weak fault has important practical significance.

Dual feedback IRC ring for chaotic waveform generation
IET Circuits, Devices &Systems, Volume 15, Issue 7, Page 595-601, October 2021., 2021 Abstract The authors have proposed an inverter resistor capacitor (IRC)‐based simple chaotic ring oscillator with dual feedback for the generation of the chaotic waveform. The proposed chaotic system uses three coupled autonomous first‐order differential equations and it can be electrically demonstrated using the complementary metal oxide semiconductor

Comparing Asset Pricing Factor Models under Multivariate t‐Distribution: Evidence from China
Discrete Dynamics in Nature and Society, Volume 2021, Issue 1, 2021., 2021 Factor models provide a cornerstone for understanding financial asset pricing; however, research on China’s stock market risk premia is still limited. Motivated by this, this paper proposes a four‐factor model for China’s stock market that includes a market factor, a size factor, a value factor, and a liquidity factor.
