Abstract:
Disclosed herein is a switch for turning on/off the connection between a first terminal and a second terminal. The switch includes a first transistor circuit configured from two transistors connected in series between the first terminal and the second terminal; and a second transistor circuit having a gate terminal connected to source terminals of the two transistors and a source terminal connected to gate terminals of the two transistors. The connection between the first terminal and the second terminal is changed over between on and off states by changing over a potential to the source terminal of the second transistor circuit between high and low levels.
