The circuit employs local voltage boosting and a new boost-and-bootstrap switch in order to allow operation under 0.4 V of supply voltage. Still, the ADC topology achieves a differential input swing of 1.6 Vpp, which is four times the supply voltage. The 0.13-μm CMOS prototype achieves an ENOB of 8.01 at 300 kSps while consuming 354 nW.
