| Abstract:To verify the performance of a type II superlattice infrared detector, a driving circuit is designed for the detector. Because the infrared detector has high sensitivity, a low noise power supply bias circuit which can optimize the layout of the circuit board is designed. The driving circuit designed according to the characteristics of a 320×256 long wave infrared focal plane array is used to provide power and bias voltages and timing and control signals for the detector assembly. The experimental results show that this driving circuit can meet the lower noise and high precision requirements of the type II superlattice infrared imaging system. |
