Abstract
A switched inductor system is provided that includes a switching regulator configured to receive an input signal and provide a voltage output, the switching regulator having one or more switches and one or more inductors. The system also includes a sensing circuit in parallel with the inductor. The sensing circuit includes a first RC circuit configured to detect an alternating current component of the voltage output and a second RC circuit configured to detect a direct current component of the voltage output.
