Abstract
A novel low-voltage (LV) switched-capacitor (SC) resonator circuit and its bandpass ΔΣ 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
