ABSTRACT:
A CMOS latch circuit having a second feedback inverter and a switching circuit to switch the second feedback inverter out of the circuit when the latch is being loaded. A first circuit implementation uses a single PFET as the switching circuit, and a second circuit implementation incorporates an NFET transistor, in parallel with the PFET. In a third circuit implementation, the switching circuit switches power to and from the second feedback inverter rather than switching the output signal of the inverter to reduce the input capacitance of the latch.
