Abstract
A differential comparator circuit is provided that includes a differential input pair, an active load, a pair of cross voltage generation devices and a pair of switches. The differential input pair has a pair of input terminals and a pair of first connection terminals. The active load has a pair of second connection terminals. The cross voltage generation devices are electrically coupled between the first connection terminals and the second connection terminals, wherein the cross voltage generation devices are configured to be electrically activated to establish a cross voltage therebetween in a reset phase and electrically deactivated to become a short circuit in an operation phase. The switches are configured to electrically couple the pair of input terminals respectively to the pair of first connection terminals in the reset phase and not electrically couple the pair of input terminals respectively from the pair of first connection terminals.
