Abstract
A comparator circuit is implemented using a simple comparator core having two gain stages integrated in a single circuit block. The circuit operates with improved speed and resolution in comparison to a conventional continuous-time comparator. Offset trimming allows for the crossing time of the comparator to be adjusted close to an ideal crossing time.
