A low-distortion delta-sigma modulator with ring amplifier and passive adder embedded SAR quantizer

Abstract

This paper presents a novel multi-bit feedforward ΔΣAD modulator for low power and high signal-to-noise-and-distortion (SNDR) application. The integrators in the modulator are realized by ring amplifiers without static current. Multi-bit quantizer and analog adder in the feedforward modulator is realized by a passive-adder embedded successive… (More)
