Abstract

The authors consider the problems that arise during the operation of the charge sensitive amplifier (CSA) in critical conditions. Simplified schemes and mathematical models of the CSA are presented in order to study the effect of noise of operational amplifier and high-resistance resistor of negative feedback loop. The dependence of the CSA noise level on the pyroelectric interference compensation value is studied. Mathematical analysis data is confirmed by computer circuit simulation.
