A differential amplifier formed on a silicon-on-insulator substrate, including means to prevent the bodies of its differential input transistors from charging to unwanted potentials in the standby state. In one aspect of the invention, the means takes the form of switching transistors inserted between the differential input transistors and their loads. In another aspect of the invention, the means takes the form of switching transistors inserted between the sources and bodies of the differential input transistors. In another aspect of the invention the means is a regulator section that holds the bodies of the differential input transistors at an appropriate potential level.
