Novel single-loop multi-bit sigma-delta modulator using OTA sharing technique without DEM

Abstract

This paper presents a novel technique to shape feedback DAC mismatch without any extra digital elements inside the sigmadelta loop by inserting an analog integrator and an out-of-loop digital differentiator. To lower power dissipation, a novel triple integrator with low capacitor mismatch sensitivity of the delay paths is proposed. As a result, the SDM with… (More)
