Abstract:
A multi-rate sigma delta digital-to-analog converter may include a signal input and a signal output, and multiple modulators. A first of the modulator may convert a digital input signal on the signal input to an analog output signal on the signal output. Subsequent of the multiple modulators may shape and cancel quantization noise received from a proceeding modulator. One of the modulators may operate at a higher frequency than does another of the multiple modulation loops.
