Abstract
The embodiments described herein provide calibration systems and methods for mixed-signal devices. Specifically, the embodiments provide systems and methods for calibrating mixed-signal devices that can facilitate effective calibration of such mixed-signal devices, including mixed-signal devices with poorly characterized nonlinearities that cannot be effectively calibrated with traditional calibration techniques. In general, the embodiments described herein calibrate by measuring output values from a mixed-signal device with a known calibration input values being applied. The measured output values are used to determine localized polynomial interpolants. Each of the determined localized polynomial interpolants is then evaluated at an uncorrected output value, and the evaluated localized polynomial interpolants are then used to generate correction values.
