Abstract
A network is connected between the drain and gate of a transistor for limiting the overshoot and controlling the waveshape of the signal produced at the drain of the transistor, when the transistor is being turned-off. The network includes a series string of zener diodes with one or more by-pass capacitors connected across one or more zener diodes for shaping the output signal produced at the drain of the transistor and for reducing electromagnetic radiation. The network also includes unidirectional conducting elements for discharging each bypass capacitor each time the transistor is turned-on. The zener diodes and the 'discharging' unidirectional conducting elements of the network may be formed as integral parts of the same integrated circuit (IC). For best results, the bypass capacitors are connected across the zener diodes closest to the gate of the transistor.
