Abstract
A method of voltage driving a load using a controlled current includes providing a negative feedback of an output current, measuring the output current on a collector of an output transistor of an output stage, comparing the measured output current with an input current to define a current difference, and providing the current difference at a base of the output transistor to provide the voltage driving.
