Abstract
In some embodiments, a calibration circuit can include a first circuit configured to generate a first output voltage based on a first reference voltage, and a second circuit configured to compare the first output voltage and a second reference voltage. The calibration circuit can further include a calibration block configured to provide an adjustment to the first circuit based on the comparison of the first output voltage and the second reference voltage, with the adjustment being configured to compensate for a change in the first reference voltage. In some embodiments, such a calibration circuit can be utilized for and/or be a part of a digital-to-analog converter for wireless audio applications.
