Abstract
A MOSFET whose back gate area is independent of a substrate is employed as a level-slicing transistor which is simultaneously used for alternately turning ON and turning OFF four analog switches in accordance with the relation between the voltages of the output terminal and inverted input voltage of the output terminal is limited to V.sub.B .+-.V.sub.th, where V.sub.th is the amplitude at the threshold level of the levelslicing transistor and V.sub.B is the bias voltage.
