In order to improve the performance of infrared system, both infrared detector and readout circuit must be packaged together and work at low temperature. A great deal of research has been done on the readout circuits of infrared detectors internationally, but there are some universal disadvantages such as unstable performance at low temperature, excessive noise of output signal and oscillation at low temperature. To improve the performance of infrared detector system, a design with a cascode CTIA and phase self compensation capacitor before CDS is developed, which is able to ensure that the circuit has a larger phase margin and a stable operating status at low temperature. Through simulation analysis, the compensation capacitance benefit is to reduce output overshoot voltage from 76 mV to 4.9 mV, the signal stability time can be decreased to 1/10 of the former. The performance of the readout circuit is tested after design and tapeout, the output noise of circuit becomes lower, the value is less than 0.5 mV. The circuit can work normally from room temperature to low temperature. The signal swing is greater than 2 V. After being interconnected with IR detector, the readout circuit can work well at low temperature and overcomes the defect of oscillation phenomenon at low temperature. The system’s electrical cross-talk is also improved obviously.
