Abstract
A sigma-delta converter may include a filter coupled to a first summation circuit and a second summation circuit. A multi bit quantizer may be coupled to the second summation circuit. A single bit digital-to-analog converter (DAC) may be included that defines a feedback path between the multi-bit quantizer and the first summation circuit. A feed-forward coefficient circuit defining a feed forward path between the first summation circuit and the second summation circuit may be included.
