Power-efficient flash ADC with complementary voltage-to-time converter

A power-efficient complementary voltage-to-time converter (CVTC) is proposed for a flash ADCs. The alternating reset direction according to the signal development direction reduces the power consumed by the reset operation and the operational frequency of the CVTC is effectively reduced by half. Accordingly, the logic circuits following the CVTC work in a time-interleaved manner, resulting in sign...
