A high-performance flip-flop circuit implementation. The flip-flop circuit comprises an "implicit" one-shot to generate a delayed clock output (407). The flip-flop comprises a delay block (405) coupled to a clock input (210). The flip-flop may be a D-type flip-flop. In a positive-edge-triggered embodiment of the flip-flop, a falling edge (540) of the delayed clock output (407) follows a rising edge (544) of a clock signal after a delay period (548). The flip-flop clocks in new data at a data input (205) in response to the clock input (210) during this delay period (548). Data is held in a storage block (450). The flip-flop has extremely good transient characteristics, especially set-up and clock-to-output times. The flip-flop consumes no static power.
