Asynchronous digitisation of transient signals from radiation detectors

摘要

The device has a comparator (110) for receiving an amplified and filtered detection signal (SA). A digital block (120) acts as a feedback loop controlling a signal (SF) based on an output signal (SB) of the comparator such that direction of variation of the signal is dependent on a state of the output signal. The block comprises an analog block (130) having given parameters. A digital module (140) estimates the signal using switching times of the output signal of the comparator and the given parameters of the smoothing filter. An independent claim is also included for a method for digitizing a detection signal from an ionizing electromagnetic radiation detector.
