1. An integrated circuit having an edge transition detector for producing an output signal at an output node in response to an input signal coupled to an input node, said edge transition detector comprising:

  • a switch coupled to said output node;

    a logic device with a first input coupled to said input node and an output coupled to a control terminal of said switch to enable said switch to conduct, thereby to effect a transition of said output signal from a first logic level to a second logic level in response to said input signal; and

    a feedback path from said output node to a second input of said logic device, wherein said feedback path disables said switch conductivity when said output signal completes said transition from said first logic level to said second logic level, and wherein said feedback path to said second input of said logic device includes an S-R flip-flop.
