In many sensor applications, a high-resolution analog-to-digital converter (ADC) is a key
block. The use of an incremental delta-sigma ADC (IADC) is often well suited for such …

This paper presents an overview of emerging circuits and systems techniques which are at
the forefront of the state of the art in ΔΣ modulators, pushing their performance forward and …

Multichannel neural amplifiers are commonly implemented with a shared reference whose
input impedance is several times lower than that of the corresponding signal inputs. This …

A charge pump using 0.13-μm CMOS process for low-voltage energy harvesting is
presented. A low-power adaptive dead-time (AD) circuit is used which automatically …

This article presents a third-order voltage-controlled oscillator (VCO)-based analog-to-digital
converter (ADC) that leverages pseudo-virtual ground (PVG) feedforwarding (FF), linearizing …

This article presents a fully dynamic scalable switched-capacitor delta–sigma modulator that
achieves a 94.1-dB dynamic range (DR). Power-and-bandwidth scalability by only changing …

This article presents a fully dynamic 2–0 multistage noise-sha** (MASH) analog-to-digital
converter (ADC) for low-power and high-precision applications. It implements the …

A 0.9-V ΔΣ modulator integrated into a 0.18-μm CMOS technology for digitizing signals in
low-power devices is presented in this paper. To do so, a cascade (multistage noise …

Over the last decade, MEMS microphones have become the leading solution for
implementing the audio module in most portable devices. One of the main drivers for the …

This article presents a nested delta-sigma modulator (DSM) structure, where an inner
analog DSM is embedded in an outer analog-digital-hybrid DSM. The outer hybrid DSM is …
