Abstract
Circuitry for transmitting signals through a transformer has an output transistor and circuitry which provides a controlled current to and from the output transistor's gate, so as to charge and discharge the gate's parasitic capacitance and increase and decrease the transistor's output current in a controlled manner. Feedback can be used to sense an output signal created by the transistor and turn off current to or from the transistor's gate when the output signal has reached a desired level. The output signal can be the voltage differential produced across an output transformer, and, where the output transformer is center-tapped, it can be the voltage differential across both halves of the center tapped winding.
