A METHOD FOR REDUCING BOTH STATIC AND DYNAMIC LINEARITY ERRORS IN A DIGITAL TO ANALOGUE CONVERTER

R. Allan Belcher

Abstract

Conventional methods for correcting linearity errors in a digital to analogue converter (DAC) rely on characterising the DAC first. This paper describes a technique that can increase linearity without characterizing the DAC. It is in principle, able to remove completely deterministic errors. As no calibration is needed the improvement can track dynamically changing errors due for example to thermal effects.
