Abstract
A method for driving an output node includes driving a control node of an output device coupled to the output node according to an input signal and using a fixed regulated voltage and a variable regulated voltage. The method includes generating the fixed regulated voltage based on a first power supply voltage, a second power supply voltage, and a first reference voltage. The method includes generating the variable regulated voltage based on the first power supply voltage, the second power supply voltage, and a second reference voltage. The method includes generating the second reference voltage based on the first power supply voltage, the second power supply voltage, a reference current, and a predetermined target voltage level of the control node of the output device. In an embodiment of the method, generating the second reference voltage includes periodically calibrating the second reference voltage.
