Abstract:
An analog signal is input to an input terminal. An analog signal is output via an output terminal. A first transistor is an N-channel MOSFET, and is provided between the input terminal and the output terminal. A first resistor is provided between the gate of the first transistor and a first fixed voltage terminal (power supply terminal), which sets the gate of the first transistor to a high-impedance state.
