PURPOSE:To decrease the number of elements of the unit circuit, by constituting the RS flip flop with a minimum of four elements through the use of complementary MOSFET and constituting D latch with a minimum of six elements. CONSTITUTION:The drain 1D of P channel MOSFET 1 and the drain 2D of N channel MOSFET 2 are connected each other, and the gate 3G of P channel MOSFET 3 and the gate 4G of N channel MOSFET 4 are connected to the junction. Further, the drain 3D of FET 3 and the drain 4D of FET 4 are mutually connected, the souces 1S and 3S of FET's 1 and 3 are respectively conncted to the plus side power supply line 5, and the souces 2S and 4S of FET's 2 and 4 are respectively connected to the minus side power supply line 6. Thus, the charge stored in the gates of complementary MOSFET's pair mutually connecting each gate and drain is alternately discharged and charged with P and N channel MOSFET's. |
