Digital self-calibration of a digital-to-analog converter

A digital-to-analog converter containing one or more ideal stages, a reduced-radix stage coupled with the one or more ideal stages, and a digital calibration logic section to operate on a calibration value. The calibration value is the difference between a first calibration constant and a second cal...

Summary:A digital-to-analog converter containing one or more ideal stages, a reduced-radix stage coupled with the one or more ideal stages, and a digital calibration logic section to operate on a calibration value. The calibration value is the difference between a first calibration constant and a second calibration constant. Digital input codes are received through the digital logic section. The calibration value is added to digital input codes with values that exceed the value of the second calibration constant. The outputs of the digital logic section are input to all stages of the digital-to-analog converter.
