摘要
高速PIN开关在通信、雷达和电子对抗系统中有着广泛的应用,然而在设计PIN开关电路时却不能通过仿真准确地得出其开关速度。提出一种新的PIN管开关速度的仿真方法,根据PIN二极管开关导通与关断时刻内部各个PIN管的状态作为判定依据,可以准确仿真计算开关的导通与截止时间。采用Strllo提出的PIN管瞬态模型进行仿真,计算结果与实际测试结果相符。该方法可准确地仿真PIN开关速度,也可以用于其他半导体控制电路的开关时间仿真。
High speed PIN switch is widely used in communication, radar and electronic counter systems. But it is diffi- cult to get out the cut-off time. A new approach of speed simulation of PIN diode switch is proposed. According to the state of each PIN diode, the switeh＇s cut-off time can be calculated accurately. Stroll＇s transient model is used to simulate the switching behavior of PIN diode, and the results consistent with the actual test data. This method can be used to simulate PIN switching speed, and also for other semiconductor control circuit＇s switching time simulation.
