摘要： A delta-sigma converter including a multiplier. The delta-sigma converter includes a feed-forward path and a feedback path providing a feedback signal. The converter output signal is multiplied in the feedback path by a mapping function, and the multiplied signal is mapped to a digital feedback signal having the same number of bits as the input signal. There is also provided a digital-to-analog converter including a delta-sigma converter consistent with the invention, and a method of multiplying a digital signal.
