Abstract
A half-latch that includes negative feedback circuitry is provided. The negative feedback circuitry causes the steady-state gain of the half-latch to remain high so that the overdrive voltage needed to change the state of the half-latch is significantly reduced. Additionally, the negative feedback is bypassed by capacitors at high frequencies so that the speed of the half-latch is substantially unaffected by the negative feedback.
