Abstract
This paper presents the first Flash analog-to-digital
converter (ADC) in standard CMOS technology that functions
from 300 K (room temperature) down to 4.2 K. It has been de-
signed to operate in cryogenic sensor systems as they are cooled
from room temperature to their final cryogenic operating tem-
perature. In order to preserve the circuit’s performance over
this wide temperature range, even in the presence of tempera-
ture-induced transistor anomalies, dedicated architecture and
switching schem
