摘要: Stable, robust, and high-resolution delta-sigma error feedback modulators, such as those used in digital-to-analog converters phase-locked loops, include an L-order noise transfer function that is provided with L+1 high-order bits from a truncation element. The stability of modulators independent the input signal. Moreover, out-of-band gain need not be limited, which improves resolution signal-to-noise ratio in-band
