Popular small satellites host individual sensors or sensor networks in space but require ground stations with directional antennas on rotators to download sensors’ data. Such ground stations can establish a single downlink communication with only o

High-resolution continuous-time delta-sigma modulators use resistive feedback DACs for low-noise operation. Such DACs have conventionally been switched at the reference end. It turns out that reference-path resistance degrades the performance of thes

Frequency Response Analysis (FRA) is a comparison based method and is useful to identify the mechanical fault in transformer winding only when the ‘healthy’ or ‘reference’ magnitude response is available. But, in practice, ‘healthy’ respo

This work proposes an static random access memory (SRAM) with column-based split cell-VSS (CS-CVSS), data-aware write-assist (DAWA), and enhanced read sensing margin in 28-nm FDSOI technology. The proposed CS-CVSS and DAWA techniques improve both hal

In this article, a novel single-phase single-stage transformerless inverter is proposed for grid-tied and standalone applications. The proposed inverter has low leakage current and can perform both buck and boost functions. Furthermore, compared to t

This article presents a low-power audio continuous-time delta-sigma modulator (CTDSM) that employs a chopped negative-R and a tri-level finite impulse-response (FIR) DAC. The noise of the first opamp is mitigated by using a negative-R at the virtual

This article presents a circuit technique to improve the power efficiency of the well-established active-RC continuous-time (CT) Delta-Sigma modulator (DSM). The technique is to add a large capacitor at the virtual ground node of the first amplifier

A single-phase transformerless full-bridge photovoltaic grid-tie inverter is presented. It utilizes 1) a virtual ground technique to mitigate ground leakage current, 2) a hybrid pulsewidth modulation (HPWM) scheme to profile the output current and pr
