Abstract
A dynamic element matching (DEM) scheme is implemented in a crawling code generator for converting a b-bit binary input code into a (2−1)-bit digital output code. A random generator determines for every conversion step a direction. A decimal difference between the current and previous binary input is calculated. The new crawling output code is determined based on the previous crawling output code, the direction and the decimal difference. The DEM scheme is used in a digital-to-analog converter such that the crawling output code switches digital-to-analog converting elements that output analog signals that are then summed to be the final analog signal.
