DUAL-USE READ-OUT CIRCUITRY IN CHARGED PARTICLE DETECTION SYSTEM

An improved readout circuit for a charged particle detector and a method for operating the readout circuit are disclosed. An improved circuit comprises an amplifier configured to receive a signal representing an output of a sensor layer and comprising a first input terminal and an output terminal, a capacitor connected between the first input terminal and the output terminal, and a resistor connected in parallel with the capacitor between the first input terminal and the output terminal. The circuit can be configured to operate in a first mode and a second mode. The capacitor can be adjustable using a capacitance value of the capacitor to enable control of a gain of the circuit operating in the first mode and control of a bandwidth of the circuit operating in the second mode.
