Abstract
A device includes a current-sensing amplifier with one output. The current-sensing amplifier includes a resistor coupled to the output. The current-sensing amplifier is designed to generate a current through the resistor. An auto-zero circuit has one input coupled to the output of the current-sensing amplifier. The auto-zero circuit is designed to iteratively adjust a second current from the output of the current-sensing amplifier through the auto-zero circuit based on a voltage across the resistor.
