Abstract
A method to reduce the integral non-linearity (INL) of a digital-to-analog converter (DAC) and a DAC implementing said method are disclosed. The method in this invention is a pseudo dynamic element matching (PDEM) method. Compared with a prior art, the method of this invention provides a better performance in glitch. Compared with another prior art, the method of this invention also guarantees that DEM will not fail even if the input digital code remains constant.
