Title: RESISTORLESS CHARGE SENSITIVE PREAMPLIFIER SYSTEM
Abstract:
The present invention relates to the resistorless charge sensitive preamplifier system for amplifying charge delivered by a particle detector (Ge), comprising: a field effect transistor (T1) having a gate, source and drain, the gate being connectable to the particle detector (Ge), for the receipt a signal from particle detector (Ge); an amplifier (OA) having an input connected to the drain or source of the field effect transistor (T1) and an output connected through a feedback capacitor (CF) to the gate of the field effect transistor (T1), in which system further comprising low frequency feedback realized with a field effect transistor (T2) having gate shorted with gate of field effect transistor (T1).
