ULTRA-LOW CLOCK POWER MULTI-BIT FLIP-FLOPS USING UNIDIRECTIONAL DEVICES
This abstract first appeared for US patent application 20240429901 titled 'ULTRA-LOW CLOCK POWER MULTI-BIT FLIP-FLOPS USING UNIDIRECTIONAL DEVICES
Original Abstract Submitted
embodiments herein relate to a multi-bit flip-flop circuit which uses unidirectional transistors to allow sharing of transistors among a set of flip-flops, while avoiding charge sharing within or between the flip-flops. clock devices in the circuit can be shared to reduce the clock transistor gate capacitance and associated power consumption. the shared transistors can provide keeper circuits and/or tri-state inverters in a primary latch and a secondary latch in each flip-flop. one example implementation uses tri-state keeper sharing. another example implementation uses tri-state keeper and/or pass gate sharing. another example implementation uses pass gate sharing and no keeper.
