Abstract
An electronic circuit device for driving a load comprises a load terminal, a control terminal and a power terminal for connection to a source of electric power. The load terminal may be in an emitter or a source circuit of the circuit device, and connects to a power supply return terminal by means of three electric elements connected in parallel, namely, the capacitance of a load, a bias current supply, and a current bypass. A voltage sensor is connected between the control terminal and the load terminal for sensing a voltage drop developed between the control terminal and the load terminal. The voltage sensor it is operative to activate the bypass to conduct current in parallel with current flow of the current source in the situation wherein the voltage drop exceeds a threshold. Thereby, the circuit device drives the load in one direction, and the current source and the bypass drive the load in the opposite correction.
