Paper Abstract

A mathematical model is given for a frequency-compensated detector/preamplifier appropriate for cryogenically-cooled infrared sensors operating under low background conditions. By use of a digital computer, this model is used to rapidly select the optimal combination of design values. These parameters include load resistance, compensation resistance, compensation capacitance, chopping frequency and detector area to meet desired specifications of noise equivalent power, frequency response, dynamic range, and level of output noise. This computer-aided optimal design approach is demonstrated using a contemporary infrared sensor application.
