Abstract
A switching circuit, a charge sense amplifier, and a photon counting device are provided. The switching circuit configured to close and open a connection between a first terminal and a second terminal of a predetermined circuit element, includes: a first transistor comprising a source connected to the first terminal, a drain connected to the second terminal, and a gate; a second transistor comprising a drain, a source, and a gate connected to the drain of the second transistor; a current source configured to supply a current flowing through the drain and the source of the second transistor, to generate a gate voltage of the gate of the second transistor; and a multiplexer configured to receive the gate voltage, a reference voltage, and a control signal, and selectively apply the gate voltage or the reference voltage to the gate of the first transistor based on the control signal.
