Abstract
An analog switch includes two complementary MOS field-effect transitors ( ) whose source-drain circuits are located in parallel between the input terminal ( ) and the output terminal ( ) of the switch. A control signal for controlling the switch is applied to the gate of the MOS field-effect transistor ( ) of the one channel type directly and to the gate of the MOS field-effect transistor ( ) of the other channel type via a negator ( ). Between the input terminal ( ) and output terminal ( ) of the switch the series source-drain circuits of three MOS field-effect transistors ( ) are inserted, whereby the MOS field-effect transistor ( ) located in the middle of the series circuit has a channel type opposite that of the other two MOS field-effect transistors ( ). The gates of all MOS field-effect transistors of the other channel type are each interconnected. The threshold voltages of the three MOS field-effect transistors ( ) of the series circuit are lower than the threshold voltages of the two complementary MOS field-effect transitors ( ) whose source-drain circuits are connected in parallel.
