Apparatus and method for an improved master-slave flip-flop with non-overlapping clocks

摘要

An improved master-slave flip-flop that is characterized by a novel clock generator. The improved flip-flop preserves the true master-slave relationship by ensuring a two step latching process is executed by non-overlapping clocks. The clock generator features an inverter in combination with a current limiter. The current limiter has the effect of shifting the trip point of the inverter such that non-overlapping clocks may be derived from a single master clock signal or a master clock signal and its complement.
