PURPOSE:To make high speed by eliminating the boosting time and to reduce the number of transistors and capacitors, in the dynamic type FF constituted with MOS transistors. CONSTITUTION:At the period t1 of spare charge, OUT and inversion OUT are reset to the ground level with the clock pulse inversion phi, the gates of transistors 5 and 6 are respectively charged to V-V1 with the clock phi through the transistors 11 and 12 and are kept completely as the same voltage with the transistor 13. When the inversion phi is kept low level before phi transfers to high level, phi is at high level and a voltage is given to OUT and inversion OUT, and the amplified signal is taken place to OUT and inversion OUT according to the state of input signal. At this circuit, since reset is made with low level of phi through the transistors 5 and 6, allowing to reduce the number of elements. |
