Abstract
A method for designing a noise shaper with a single loop distributed feedback delta-sigma modulator includes following steps: (a) determining a delta-sigma modulator comprising a plurality of parameters according to an order of the noise shaper; (b) deriving a noise transfer function comprising a plurality of coefficients corresponding to the parameters of the delta-sigma modulator according to the delta-sigma modulator; (c) determining a high-pass filter corresponding to the delta-sigma modulator according to a default requirement; (d) solving the coefficients of the noise transfer function according to the high-pass filter; and (e) feeding the solved coefficients in step (d) into the parameters of the delta-sigma modulator for completing the noise shaper.
