Abstract

An 8b 1.2GS/s single-channel SAR converter is implemented in 32nm CMOS, achieving 39.3dB SNDR and a FOM of 34fJ/conversion-step. High-speed operation is achieved by converting each sample with two alternating comparators clocked asynchronously and a redundant capacitive DAC with constant common mode. Background comparator offset compensation is implemented. The ADC consumes 3.1mW from a 1V supply and occupies 0.0015mm2.
