Abstract
A current sensor circuit is provided. The circuit includes a voltage integration circuit connected in parallel to an inductive element. The voltage integration circuit is configured to integrate an inductive element current through the inductive element between a first potential at a first end of the inductive element and a second potential a second end of the inductive element. The voltage integration circuit provides a voltage analog of the inductive element current. A voltage current convertor circuit is electrically connected to the voltage integration circuit. The voltage current convertor circuit is configured to convert the voltage analog of the voltage integration circuit to an output current that is proportional to the inductive element current.
