AB  - In this paper a method for minimizing the total harmonic distortion (THD) is presented for a class-D output stage by optimizing a loop filter. A second-order filter is chosen to create large error suppression through the audio band while keeping the overall system complexity low. The stability of the optimized loop is examined to ensure proper operation. SIMULINK simulations are given to verify the theory introduced.
