Abstract

A 30k-gate dynamic element matching circuit for bandpass modulators with a 4-bit quantizer is designed by using 0.35-μm CMOS technology. Second-order bandpass mismatch-shaping algorithm improves the signal-to-noise ratio by ~30dB (~5 bit). The core circuit area and the estimated operation speed were 1.44 mm² and 20 MHz, respectively.

Automatic tuning of digitally-controllable positive-feedback OTAs in continuous-time sigma---delta modulators

This paper proposes a technique suitable for on-chip tuning of digitally-tunable positive-feedback operational transconductor amplifiers in a continuous-time sigma---delta modulator (CT-SDM) with active-RC integrator stages. The work we present relies ...
Multibit delta-sigma modulator with noise-shaping dynamic element matching

This paper describes a fifth-order multibit low-pass delta-sigma modulator employing a proposed noise-shaping dynamic element matching (NS-DEM) technique to remove DAC nonlinearity error. Unlike most existing DEMs that trade SNR for SFDR, the proposed ...
All-digital gated ring oscillator $$\Delta \Sigma$$ΔΣ modulators

This paper presents all-digital time-mode $$\Delta \Sigma$$ΔΣ modulators. The proposed modulators consist of a voltage-to-time integrator, a seven-stage gated ring oscillator functioning as a 3-bit quantizer, and seven digital differentiators. A ...
