    • PURPOSE: A latch circuit is to reduce a number of transistor to be needed in a static flip-flop circuit. CONSTITUTION: A dynamic D-typed flip-flop circuit comprises a master latch(1) and a slave latch(2). The master latch includes a P-typed dynamic threshold MOS transistor(3) and an inverter(4). The slave latch includes an N-typed DTMOS(Dynamic Threshold Metal Oxide Semiconductor) transistor(5) and an inverter(6). The P-DTMOS transistor is provided at its gate with a clock signal. The P-DTMOS transistor is applied with an input data signal, and outputs the data signal to the inverter according to the clock signal. The inverter inverts the received signal and outputs an inverted signal. The N-DTMOS transistor is provided at its gate with a clock signal. The N-DTMOS transistor is applied with a signal, and outputs the signal to the inverter according to the clock signal. The inverter inverts the received signal and outputs an inverted signal.
