Abstract
In a constant voltage generating circuit, a predetermined voltage outputted by voltage applying means connected between first and second power source terminals is simultaneously applied to the control electrode of a first MOS transistor of a first polarity and the control electrode of a second MOS transistor of a second polarity which are provided complementarily, and a voltage obtained by subtracting the threshold voltage of the first MOS transistor from the potential at the control electrode of the first MOS transistor is applied to the control electrode of a third MOS transistor of the second polarity while a voltage obtained by adding the potential at the control electrode of the second MOS transistor to the threshold voltage of the second MOS transistor is applied to a fourth MOS transistor of the first polarity, so that each of the third and fourth MOS transistors is operated in the critical state between the conductive state and the non-conductive state, whereby positive or negative noise voltage included in the output voltage of the circuit is quickly eliminated.
