ABSTRACT:
An output signal of a logic portion is inputted to the gate of FET inside an output buffer portion to inverse the signal polarity by this FET and is outputted through a bipolar transistor effecting an emitter follower operation or the like. An FET controlled by a clock signal is disposed between the base of the bipolar transistor and the ground and an FET which is turned ON during a pre-charge operation and when the bipolar transistor is OFF during logic calculation is disposed between the emitter and the ground so as to short-circuit the emitter and the ground during the pre-charge operation. In this manner, higher operation speed, higher integration density and high operation margin can be accomplished without losing the characteristic features of a Bi-CMOS dynamic logic circuit in its high operation speed and low power dissipation.
