Abstract

A dynamic comparator includes two sets of input transistors of opposite conductivity types, where a control electrode of one transistor of each set is coupled to a first input of the comparator and a control input of a second transistor of each set is coupled to a second input of the comparator. The comparator includes bypass transistors for pulling current electrodes of either the first set or second set of input transistors to a power supply terminal depending which input voltage is higher as determined by the output.
