Abstract

Aspects for a flip-flop circuit are described herein. As an example, the aspects may include a first passgate, a first latch, a second passgate, and a second latch. The first latch may include a first inverter and a first logic gate. The first logic gate may further include a second inverter and at least one voltage reducing component. The voltage reducing component may be an N-channel transistor or a P-channel transistor. Similarly, the second latch may include a third inverter and a second logic gate. The second logic gate may further include a fourth inverter and at least one voltage reducing component.
