Abstract
A method for calibrating a successive-approximation analog-to-digital converter (ADC) includes configuring the successive-approximation ADC in a calibration mode of operation. The method includes, while in the calibration mode of operation: determining a digital code corresponding to a programmable capacitance of the successive-approximation analog-to-digital converter, and storing the digital code corresponding to the programmable capacitance in a storage element of an integrated circuit die including the successive-approximation ADC. The programmable capacitance may be a gain tuning capacitance, a bridge tuning capacitance, an offset capacitance, or a monotonicity tuning capacitance.
