摘要
采用SACM-APD电路模型以及对前置放大电路的分析,建立了APD前置放大模块电路模型,并对模型进行瞬态特性和交流特性仿真分析。模拟得到响应度约为400kV/W;信号沿上升下降时间为6ns,-3dB带宽约为73MHz,与研制的APD前置放大模块实际试验测试值相吻合。
By applying SACM-APD circuit model and analyzing the preamplifier circuit, it models the APD preamplifier module circuit and simulated the instantaneous and AC characteristics. Simulation responsibility is about 400KV/W; rising and descending time of signal edge is 6 ns, - 3dB bandwidth is about 73MHz. The result is as same as the actual testing value of fabricated APD preamplifier module circuit.
