ABSTRACT:
In a reference voltage generation circuit consisting of a capacitor, a reference voltage source for generating a predetermined voltage for charging the capacitor and a voltage polarity switching circuit for selectively inverting or not inverting the charged voltage of the capacitor to produce an output voltage at an output terminal, and capable of being fabricated in a semiconductor integrated circuit, the improvement wherein the voltage polarity switching circuit includes a second capacitor for compensating for an error between positive and negative reference voltages due to the stray capacitors.
