ABSTRACT:
An electronic D-type flipflop includes two storage elements and two transmission gates wherein each gate includes only one MOS transistor. In the first gate the MOS transistor is of a first conductivity type and it is of a second conductivity type in the second gate. The MOS transistors each receive the same clock signal at their gate electrode. Because it is not necessary to form an inverted clock signal, problems due to phase differences between the clock signal and its inverse are precluded. Each of the storage cells includes a pair of inverters which are coupled end-around. The transmission characteristic of the forward inverting circuit is adapted in such a way that it compensates for the voltage drop across the preceding transmission gate. Only a small substrate surface area will be required when the flipflop is used in an integrated circuit.
