Abstract :
This paper presents a novel implementation of a 6th order cascade of lowpass and bandpass MASH ΔΣ modulators architecture intended for wideband and multi-standard applications. It demonstrates the improvement in dynamic range of about 22 dB over its cascade of lowpass stages only counterpart
