A voltage comparing circuit has a current pass forming circuit connecting the one main terminals of a first and second field effect transistors which input two input signal voltages on their control terminals, respectively. The current pass forming circuit, respond to the voltage difference between the two input signals, forms an instantaneous current pass between the one main terminals of the first and second transistors to cancel out the charging and discharging current of the associated transistors.
