Abstract

A 10b flexible SAR ADC is presented incorporating a selfquenched dynamic bias comparator and a self-triggered asynchronous delay line. The ADC is fabricated in 65nm CMOS, occupies 0.04mm2 and has an ENOB > 9bit and SFDR > 66dB for sampling rates from 0.2 to 8MS/s at supply voltages respectively from 0.7V to 1.3V with a Walden FoM from 0.35 to 2.5fJ/conv-step.
