A Low-Power Sigma-Delta Modulator for Healthcare and Medical Diagnostic Applications
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2021This paper presents a switched-capacitor Sigma-Delta modulator designed in 90-nm CMOS technology, operating at 1.2-V supply voltage. The modulator targets healthcare and medical diagnostic applications where the readout of small-bandwidth signals is ...

A Novel Structure Optimizer Based on Heuristic Search for Delta-Sigma Modulator in Mobile Fronthaul
IEEE Photonics Technology Letters, 2022In this letter, a novel delta-sigma modulator structure design method based on the genetic algorithm is proposed. Compared to the widely adopted R.Schreier’s method, the proposed approach can significantly reduce the in-band quantization noise ...

A Second-order Sigma-delta Modulator with a Hybrid Topology in 180nm CMOS
IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering, 2020Sigma-delta analog-to-digital converters (ADCs) are known as a good choice for high-quality low-to-medium frequency data acquisition systems. In this work, Cadence Virtuoso tools were used to design main components of a switched-capacitor sigma-delta ...

Analysis and Design of an Audio Continuous-Time 1-X FIR-MASH Delta–Sigma Modulator
IEEE Journal of Solid-State Circuits, 2020We combine a first-order single-bit CT $\Delta \!\Sigma \text{M}$ employing finite impulse-response (FIR) feedback with a 1-bit second-order $\Delta \Sigma $ back end to achieve a modulator with maximum stable amplitude (MSA) that is close to full ...
