Abstract
A dynamic element matching method for a multi-unit-element digital-to-analog converter having unit elements comprises several steps. An element selection probability is determined as a function of a number of the unit elements and a digital signal. Next, loop filter output signals are generated as a function of the determined element selection probability and control signals for the unit elements. Certain ones of the unit elements are selected as a function of the generated loop filter output signals. The selected certain ones of the unit elements are activated for output of the converter.
