A mixed signal processing unit with non-linear feedforward paths (36, 38) to improve total harmonic distortion "THD" and noise characteristics of the processor. Specifically the processor includes a first integrator stage (14) configured to receive an input signal and configured to generate a first integrated signal in response thereto, a second integrator stage (16) coupled to the first integrator stage (14) and configured to generate a second integrated signal from the first integrated signal, a sampling stage (22) coupled to the second integrator stage (16) and configured to sample the second integrated signal received from the second integrator stage (16) at a sample frequency and to generate a logic signal, and a non-linear feed-forward path (36, 38) coupled between the first integrator stage (14) and the sampling stage (22).
