Abstract

A system may include an output stage comprising a single-ended driver for driving a load at an output of the output stage, a loop filter coupled at its input to the output of the output stage and configured to minimize an error between a target current signal received by the loop filter and an output current driven on the load, and control circuitry configured to, when the load current is driven in a manner such that the load current changes polarity, reset a state variable of the loop filter.
