Abstract :
A SAR ADC is designed to operate from room temperature down to 4.2K, as needed by cryogenic sensor systems. The ADC is robust to cryogenic temperature-induced transistor anomalies. It has an INL of -0.8 (0.5)LSB and DNL of 1.1 (0.4)LSB at 4.2K(300K). It draws 70muA for a 200pF output capacitor at 3kHz sampling rate and 5V supply
