Abstract

A circuit for switching and transmitting alternating voltages comprise an MOS transistor, the pn-junctions which surround the source and drain regions being biased in a blocking direction in the driven condition of the transistor, correspondence between the potential difference between gate and alternating voltages and the required drive voltage of the transistor being achieved by a circuit which largely synchronizes gate voltage changes with the alternating voltage to be transmitted.
