ABSTRACT:
CMOS buffer circuits with reduced short circuit current. In the CMOS buffer circuit, an output stage drives an output terminal and comprises a first output transistor of a first conductive type and a second output transistor of a second conductive type. An output driving unit produces a first signal to turn off the first output transistor according to a delay signal. A bidirectional delay unit is controlled by the input signal to turn on the second output transistor after the first output transistor be turned off. In the bidirectional delay unit, a bidirectional logic unit generates two logic signals according to an inversion signal of the input signal, first and second bidirectional buffers are coupled to the output driving unit, generating a second signal to turn on the second output transistor according to the input signal and the two logic signals.
