A circuit system includes a current sensor circuit, a subtractor circuit, a multiplier circuit, and a divider circuit. The current sensor circuit generates a current sense signal that indicates a current through an inductor. The circuit system generates a current value based on the current sense signal. The subtractor circuit determines a voltage difference across the inductor. The multiplier circuit multiplies the voltage difference by a time period that the voltage difference is applied across the inductor to generate a product. The divider circuit divides the product by the current value to generate an estimated inductance of the inductor.
