This paper presents an analytical modeling of the mechanisms of total harmonic distortion (THD) of second-order based single-feedback and double-feedback Class-D amplifiers (CDAs). We show that the overall THD in these closed-loop CDAs comprises the THD of their open-loop counterparts reduced by the...
