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, com-pensation 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.
