Abstract

An 8-bit 400MS/s 2-bit per cycle (2b/C) Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) is fabricated in 65nm CMOS. With the implementation of a low-power and small-area resistive DAC and associated highly integrated circuit implementation, the proposed SAR ADC achieves rapid conversion rate, low-power and compact area leading to SNDR of 44.5dB and SFDR of 54.0dB, at 400MS/s with 1.9MHz input. The measured FOM is 73fJ/conversion-step at 400MS/s from 1.2V supply and 42fJ/conversion-step at 250MS/s from 1V supply. The active area with the digital calibration is 0.028mm2.
