Method and apparatus for locking self-timed pulsed clock

摘要

A method and apparatus for generating multiple locked self-timed pulsed clock signals is disclosed. Race margins are reduced over separate clock generating circuits by sharing the necessary delay circuit elements between the multiple clock generating circuits. An edge is gated with a delayed edge to form the first clock pulse. A subsequent second clock pulse is generated by gating a partially-delayed edge with the first clock pulse, which minimizes race margins and pulse evaporation.
