A sigma-delta modulator includes a front portion and a hybrid portion to form a loop filter. The front portion includes integrator(s) and feed-forward path(s), and is arranged to provide a front signal by combining signals of the integrator(s) and feed-forward path(s). The hybrid portion is coupled to the front portion, and arranged to provide a filtered signal by combining an integration of the front signal and a weighting of the front signal. The filtered signal is quantized, converted from digital to analog, and fed back to the loop filter.
