ABSTRACT:
An amplifier circuit controls the output current through an inductive load. A signal is amplified by one or more op amps, and sourced into a back to back coupling of an NPN transistor and a PNP transistor. In a positive circuit segment, current is sourced to an inductive load, and in a negative segment, current is sunk from the inductive load. The current at the output of the inductive load flows through a resistor, and the resultant voltage drop is negatively fed back to the op amp.
