Abstract
An electronic integration circuit comprises an integrator input element that provides a final power stage of the electronic integration circuit and provides a constant drain current in a direct current state that controls a current of the first stage driver; and an inductive load driver constructed and arranged to drive an inductive element as a voltage follower stage. The inductive load driver processes a linear gate current to control a current output to the inductive element. A capacitor is between the first stage driver and the integrator input element. A sum of a gate-source voltage of the first stage driver and a gate-source voltage of the integrator input element is provided as an integrator input to the capacitor. The capacitor performs a linear current ramp integration operation to provide a first exponential voltage shape across the inductive element required for driving the inductive element in accordance with the controlled current output in a second exponential voltage shape.
