Abstract :
A 0.9V third-order 1.5bit delta-sigma ADC with simple dynamic element matching (DEM) is presented. A fully-differential low-voltage double-sampling structure avoids use of clock boosting or bootstrapping. It operates from 0.65V to 1.5V supply with minimal performance degradation. The prototype IC implemented in a 0.13mum CMOS process achieves 92dB DR, 91dB SNR and 89dB SNDR, while consuming 1.5mW from a 0.9V supply
