Abstract
The present invention is a technique for dynamic element matching used in digital-to-analog converters (DAC's). An analog-to-digital converter (ADC) converts an analog signal into a digital code. A current-mode randomizer randomizes the digital code based on a control word provided by a pseudo random number generator. A digital-to-analog converter (DAC) converts the randomized digital code into an analog signal.
