METHOD AND APPARATUS FOR CONTROLLING NODE VOLTAGES DURING START-UP OF A DRIVER CIRCUIT TO FACILITATE BIASING OF THE DRIVER CIRCUIT

Abstract: voltages and currents associated with a driver circuit associated with a diode can be controlled during start up of the driver circuit. the driver circuit can comprise transistors that can satisfy a defined bandwidth specification in connection with driving an electrical signal for the diode. during start up, start-up controller component can control voltage levels applied to gates or backgates of transistors to maintain operating voltage levels associated with transistors at or below a defined voltage level as bias current level is incrementally increased to target bias current level, and/or start-up reference voltage level is incrementally increased to facilitate incrementally increasing an anode voltage level of an anode voltage associated with the diode. the driver circuit can supply the electrical signal to the diode based on the bias current, which can facilitate operation of the driver circuit.
