Abstract

In this paper, according to the characteristics of TDI infrared focal plane array output signal, a novel signal processing system based on AC coupling technology is proposed. Firstly, the output signal characteristics of TDI infrared focal plane array are analyzed. Secondly, the signal processing system based on AC-coupled technology is introduced. The designed system is consist of high pass filter circuit, signal conditioning circuit, differential input analog to digital converting circuit and digital data processing circuit. Thirdly, the designed system is simulated and tested. Simulation and test results show that the novel design idea of signal processing circuit is reasonable and feasible. Compared with the traditional design, the system has the characteristics of high common mode noise rejection, low temperature drift and low power consumption.
