ABSTRACT:
In a driving circuit for generating driving signals for controlling and switching on and off a first output element employed in an output circuit for generating a high-level output signal and a second output element employed in the output circuit for generating a low-level output signal in a mutually complementary manner, the conductance of the driving circuit is controlled so that it increases gradually with the lapse of time. By sequentially controlling the conductance of the driving circuit for generating the driving signals, the rates of change of the driving signals can be controlled in a smooth and stable manner and output currents can thus be changed smoothly to result in high-speed operation of an output signal with a reduced amount of noise.
