Abstract :
A circuit has been designed and proven successful in protecting devices from sudden full power activity. This has been accomplished by using an active device as a varying resistance dependent on the supply voltage. The active device first appears as a large resistance and slowly decreases to a near-zero resistance, allowing all the voltage of the supply to be seen at the load. Other irregularities such as amplitude variation may be detected by a controlling circuit, which would also vary the gate-to-source voltage accordingly
