This is a processing circuit for a spectrometry chain including a particle radiation detector (), including a charge preamplifier stage () receiving a current (I) from the detector, representative of the amount of charges emitted by a particle which has interacted with the detector, and an integrator stage (). A differentiator stage () is connected between the charge preamplifier stage () and the integrator stage (), the differentiator stage () receiving a signal (V) from the charge preamplifier stage () and delivering to the integrator stage (), a signal (V), image of the detector current (I), the integrator stage () delivering, an image (V) of the amount of charges emitted by a particle which has interacted with the detector. Application notably to the high energy single channel probes.
