Low-voltage low-sensitivity switched-capacitor bandpass /spl Delta//spl Sigma/ modulator

摘要

A novel low-voltage (LV) switched-capacitor (SC) resonator circuit and its bandpass /spl Delta//spl Sigma/ modulator implementation are presented. The proposed circuit not only uses lower supply voltage but also reduces the errors due to analog imperfections. Hence, these circuits may be suitable for submicron LV CMOS process in the next generation of AM and FM digital radio and GSM receivers.
