  • Abstract
    The ADC-SAR is fabricated in a 0.18mum 2P5M CMOS process. This SAR-ADC converter achieves 56fJ/conversion-step FOM with 58dB SNDR. It uses a comparator, named time-domain comparator, that instead of operating in the voltage domain, transforms the input and the reference voltages into pulses and compares their duration.
