Abstract
A digital-to-analog converter (DAC) calibration system for calibrating N DAC cells in a DAC, where N can be an integer number of DAC cells greater than 2, can include a processor, which can be configured to configure the DAC to generate N reference outputs, configure the DAC to generate N calibration outputs, and determine N overall error values corresponding to a difference between respective individual ones of the N calibration outputs and the N reference outputs. The processor can also be configured to determine, such as using the N overall error values, a cell error value for each of the N DAC cells.
