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.

Front-end electronic circuitry for a photon counting application

A voltage-controlled ring oscillator (VCRO) and a VCRO-based sigma delta modulator having capability of enabling and disabling the VCRO cells. A VCRO includes a plurality of inverters coupled in a ring and a transition detector. The transition detector detects a transition of a first inverter and sends a control signal to enable a second inverter if the transition of the first inverter is detected. The transition detector may include a comparator configured to compare an input and an output of an inverter(s) to detect the transition of the first inverter and a latch configured to hold the control signal until it is reset.
