Abstract
A metal-insulator-semiconductor type integrated circuit includes a semiconductor substrate of a first conductivity type and a power supply for a back-gate bias. The substrate is connected to the power supply by a switching means. A region of a second conductivity type, which is grounded, is formed on a major surface of the substrate. The potential of the semiconductor substrate is clamped at a predetermined level by a clamping means connected between the above-mentioned region and the substrate.
