Aiming at the problem of signal floating and non-consistency of the three-stage thermoelectrically cooled photoconductive (PC)HgCdTe Infrared detectors,the causes are analyzed and studied.The necessity of output consis-tency and signal stabilization is pointed out.This paper focuses on the influence of adjusting the bias current on the output voltage.It is used the zero-calibration technology,the signal synthesis and the restoring technology to eliminate and control the voltage floating .
