Abstract :
The authors present a computer-aided analysis model for the prediction of the response of a dual gate MOSFET VHF amplifier to electrostatic discharge (ESD) induced transient electromagnetic (EM) fields. With the help of the frequency spectrum of ESD generated electric field, the frequency-dependent y-parameter set for the device, and the antenna parameters, the model predicts the time-domain response for a given tuned frequency and bandwidth of the VHF amplifier. It appears that the amplifier responds at its tuned frequency during the steep rising edge of the electric field. The amplitude of response decreases sharply with increase in distance from the ESD source
