Abstract
A fully dynamic SAR ADC is proposed that uses passive charge-sharing and an asynchronous controller to achieve low power consumption. No active circuits are needed for high-speed operation and all static power is removed, offering power consumption proportional to sampling frequency from 50MS/s down to 0. The prototype implementation in 90nm digital CMOS achieves 7.8 ENOB, 49dB SNDR at 20MS/s consuming 290 muW. This results in a FOM of 65fJ/conversion-step.
