Abstract
A system and method is disclosed for providing a strobed comparator with reduced offset and reduced charge kickback. The strobed comparator circuit comprises a differential pair of transistors coupled to a first switch circuit, a regenerative latch circuit, a first strobe signal line coupled to the switch circuit and a second strobe signal line coupled to the regenerative latch circuit. The first and second strobe signal lines provide separate strobe controls. The differential pair of transistors reduces the charge kickback effect by remaining in an 'on' state. The differential pair of transistors is enabled when the regenerative latch circuit is in a reset condition and the regenerative latch circuit is enabled when the differential pair of transistors is in a saturation condition.
