In this paper a bandpass MASH (multi-stage noise shaping) sigma-delta (RD) modulator is presented. A SNR (signal to noise ratio) of at least 85 dB (equivalent to a resolution of 14 bits) has been achieved over a 5 MHz band around an intermediate frequency (IF) of 20 MHz using a clock frequency of 80
