Abstract
In a flip-flop circuit which includes an input section using a dynamic circuit and an output section using a static circuit and which captures data during a period of a pulse width shorter than a clock cycle, the number of transistors, circuit area and power consumption are reduced. In FIG.an output signal of an inverter circuit INVconstituting a latch circuitconnected to the output terminal of an input sectionis used as an input signal of a control sectionThus, a control signal output from the control sectionto the input sectionis stabilized, thereby suppressing unnecessary operation of circuit elements and reducing unnecessary power consumption. In addition, the configuration of the control sectionis simplified. As a result, the number of transistors constituting the circuit and the circuit area can be reduced.
