Abstract:
A latch circuit. The latch circuit may include an input circuit, a precharge circuit, and a transfer circuit. The precharge circuit may precharge a first node during a first phase of a clock signal. Based on an input signal received at a first logic value, the input signal may drive the first node to a second logic value during the second clock phase. The transfer circuit may include a discharge circuit that is active during an evaluation phase beginning at a delay time subsequent to the clock signal entering the second phase and ending when the clock signal re-enters the first phase. The transfer circuit may also include pull-up and pull-down transistors, one of which may drive a logic value to a second node during the evaluation phase.
