Abstract
A flip-flop circuit has a master circuit including a static flip-flop with a feedback loop, and a slave circuit including a dynamic flip-flop. In the flip-flop circuit, a clock signal is applied to the master circuit and the slave circuit. A clock width of the clock signal is determined by a time period from a clock edge for taking data into the master circuit to another clock edge for closing the master circuit, and is set to less than a given time period.
