摘要
A system and method dynamically selects digital-to-analog (DAC) circuit elements to provide a True differential-output delta-sigma (DeltaSigma) DAC. The sign and magnitude of a received N-bit input code is determined. If the input code comprises a positive value, m+r circuit elements are selected from a plurality of circuit elements by a positive element selector, in which comprises a number of rotational elements, and r circuit elements are selected by a negative element selector. Each selected circuit element comprises a circuit element that was not selected for an immediately preceding received input code and has a corresponding minimum usage count value. If the input digital code comprises a negative value, m+r circuit elements are selected by the negative element selector, and r circuit elements are selected by the positive element selector. The circuit elements are capable of being configured as positive or negative circuit elements.
