Abstract

PURPOSE:To prevent a high frequency noise and ringing due to switching from being generated keeping the high speed property of the operating speed of a circuit, by starting the trun-ON of an auxiliary switching device, etc., to an inversion side with an output switching device, etc., and separating it from the output switching device by turning OFF when its output exceeds a threshold voltage in a circuit at a succeeding stage. CONSTITUTION:The auxiliary switching device 4 or circuit is connected in parallel with the output switching devices or circuits 1 and 2 used in a buffer circuit, and switching speed is accelerated by setting the auxiliary switching device or circuit connected in parallel at an ON state until the output voltage of the buffer circuit arrives at the threshold value of an input circuit connected to the succeeding stage. And after it arrives at the threshold value, the switching speed is decreased by turning OFF the auxiliary switching device 4 or circuit connected in parallel and separating it from the output switching device, and an output waveform with a few amount of high frequency component can be obtained by decreasing the inclination of the waveform at a time when an output voltage approaches the voltage of a power source terminal. And it is possible to prevent the ringing from being generated by decreasing the inclination of the output voltage waveform of the buffer circuit in the neighborhood of the voltage of the power source terminal.
