A 10b 160MS/s 84mW 1V Subranging ADC in 90nm CMOS

A 10b 160MS/S subranging ADC with THA is implemented in a 90nm digital CMOS process. Noise averaging and an auto-zeroed comparator are used in the fine converter to achieve low noise and offset at low power dissipation. The prototype converter achieves an ENOB of 9.1b for an 80MHz input and consumes 84mW from a 1V supply
