odeling of a Double-Sampling Switched-Capacitor Bandpass Delta-Sigma odulator for ulti-Standard Applications

This paper presents an improved non-ideal model of a switched-capacitor bandpass delta-sigma modulator with tunable resonators, noise-coupling and 4-bit quantizer. Considering operational amplifier nonideal effect, clock jitter, noise, double-sampling and multi-bit quantizer capacitor mismatch effect, behavioral simulation in simulink shows that it provides 83.4dB, 67.5dB, 80.2dB, 41.0dB Signal-toNoise-and-Distortion ratio (SNDR) and 84dB, 68dB, 80dB, 55dB dynamic range (DR) for GSM, WCDMA, TDSCDMA and WLAN respectively.
