DIGITAL TO ANALOG CONVERTER

摘要

A digital to analog converter comprises a plurality of conversion elements as well as a reference conversion element and further comprises mismatch calibration unit for calibrating at least one of the conversion elements in response to a comparison of that element's output with the output of the reference conversion element. The mismatch calibration unit calibrates the source with respect to static and dynamic mismatch by determining under varying circumstances the difference between outputs from a conversion element and reference conversion element.
