Abstract
A front-end electronic circuitry for a photon counting application includes a charge sensitive amplifier including an amplifier circuit and a capacitor being arranged in a feedback path between the input side and the output side of the amplifier circuit. A controllable switch is arranged in parallel to the capacitor. The circuitry includes a delay circuit to provide a delay circuit output signal being a time-delayed representation of the charge sensitive amplifier output signal. An output signal generation circuit is configured to generate the output signal by subtracting the delay circuit output signal from the charge sensitive amplifier output signal.
