摘要: A new technique for designing an LC bandpass delta-sigma modulator is presented. This method based on pulse shaping of a DAC output signal such that one can realize desired (arbitrary) loop transfer function. Especially higher-order modulators where extra sections are added, sufficient number parameters provided in the feedback loop. It shown by creating more degrees freedom achieve maximum SNR given order without constraining noise function modulator.
