Research on Surge Suppression of Timing Fuze Timing Starting Point Based on NMOSFET Device

Abstract

When the timing fuze verification equipment simulates the timing fuze starting signal, the transient surge will interfere with the starting signal, resulting in inaccurate timing starting signal detection and time error. Through the Multisim process simulation of the timing starting point signal simulation module in the device, combined with the 'Miller platform' effect of the NMOSFET device, the value of the parallel capacitor CGD’ of the designed transient surge suppression circuit is studied. When CGD’ is 0.2uf, it can effectively suppress the surge, thus ensuring the accuracy of the timing starting point of the timing fuze.
