Abstract
Systems and methods are provided for architectures for an analog feedback class D modulator that increase the power efficiency of the class D modulator. In particular, systems and methods are provided for an analog feedback class D modulator having a digital feed-forward loop. The digital feed-forward loop allows for removal of signal content from an input to an analog-to-digital converter, such that the ADC processes just noise and/or error. Using the techniques discussed herein, the loop filter is low power as it processes error content but not signal content.
