Abstract
A system may include a pulse-width modulation mode path configured to drive a load at an output of the system in a first mode of operation, a linear mode path configured to drive the load in a second mode of operation, a common mode control feedback loop configured to set a value of a common mode output signal at the output in the second mode of operation, and an auxiliary circuit coupled to the common mode feedback control loop and configured to maintain a state of the common mode feedback control loop during the first mode of operation as the state was or will be during the second mode of operation.
