Abstract
In some embodiments, an audio amplifier can include an input node for receiving a digital signal, and a controller coupled to the input node through a feed-forward path. The controller can be configured to generate a driving signal based on the digital signal. The audio amplifier can further include a driver configured to provide an amplified signal at an output node based on the driving signal, and a feedback circuit that couples the output node of the driver to the controller. The feedback circuit can be configured to provide a feedback signal for comparison with a reference signal representative of the digital signal to generate an error signal, such that the feedback circuit provides a form of the error signal to the controller for adjustment of the digital signal.
