Abstract
Disclosed is a novel circuit technique that will significantly improve the noise margin of a passgate latch design. The circuit technique consists of a passgate latch with additional circuitry for sensing the occurrence of coupled noise and then turning on a current mirror that injects current into the latch internal node to stabilize the latch. The circuit further includes a disabling system for disabling the additional circuitry during normal operation of the passgate latch.
