Abstract
A low power preamplifier solution for use with the rs-p4-0332-203r4 resistive charge distribution neutron detectors is presented in this work. The effects of the ground input impedance caused by the chip and the ground signal undershoot caused by the blocking capacitance are evaluated via simulations. For reference, a reasonable parameter configuration in the structure of a passive filter is sufficient to suppress the effects of both the input impedance and the undershoot. The power per channel in the preamplifier is limited to a maximum of 39 mW. Finally, measurement resolution of 6.8 mm is obtained for the detector.This publication has 7 references indexed in Scilit:
