ABSTRACT:
A switching circuit for an FET transistor includes a controlled current circuit coupled to the gate of the FET. The input to the controlled current circuit represents a desired rate of change of gate voltage of the FET and is generated by a circuit responsive to the average specific transconductance of two FETs of similar specific transconductance operating at different drain circuit densities.
