A 5 bit 1.75 GS/s flash ADC is realized in 90 nm CMOS. It uses a comparator array with built-in imbalance and offset calibration to lower power consumption. The SNDR is 30.9 dB at low frequencies and gradually degrades to 28.2 dB at 2 GHz. The ADC occupies 280 um by 110 um and draws only 7.6 mA from a 1 V supply yielding an energy efficiency of 0.15 pJ/conversion step.
