Abstract:
A switch circuit includes: a sampling transistor including a source connected to an input node and a drain connected to an output node; a control circuit which is connected to a gate of the sampling transistor and configured to control turning on or off of the sampling transistor; a voltage holding circuit which is provided between the gate and the source of the sampling transistor and configured to maintain a voltage between the gate and the source of the sampling transistor constant when the sampling transistor is turned on; and a protection circuit which is provided in parallel to the control circuit and configured to lower a voltage that is applied to the gate of the sampling transistor when the sampling transistor makes a transition from on to off.
