Method and latch circuit for implementing enhanced performance with reduced quiescent power dissipation using mixed threshold CMOS devices

摘要

A method and latch circuit for implementing enhanced performance includes critical data and clock paths and non-critical sections. A low voltage threshold (LVT) transistor is used only in the critical data and clock paths. The non-critical sections are implemented with regular VT, (RVT), or low leakage (LLD) transistors. The latch circuit advantageously is implemented using LVT devices in the internal critical paths of the latch and RVT output buffer transistors.
