Abstract
A flip-flop includes an input interface, a first latch, a third inverter, and a second latch. The third inverter and the fifth inverter include first transistors of a first type formed between a first power contact and a second power contact supplied with a power supply voltage on first-type fins, and second transistors of a second type formed between a first ground contact and a second ground contact supplied with a ground voltage on second-type fins.
