Abstract
An apparatus includes a first transistor including a first gate, a first drain and a first source. A second transistor includes a second gate and a second source, the second gate is coupled to a first current source configured to generate a linear current ramp, the second source is coupled to the first gate and a second current source configured to generate a constant current through the second transistor determined by a sampled voltage between the first gate and the first source. A third transistor includes a third gate and a third source, the third gate is coupled to the first drain, and the third source is coupled to an inductive load, wherein the third transistor is configured to source a load current to the inductive load in response to an integration of the linear current ramp. A first capacitor is coupled between the third source and the second gate.
