Abstract
A system includes a multiplying digital-to-analog converter (MDAC). The system also includes an input-side component coupled to the MDAC and configured to provide a code to the MDAC. The system also includes a reference voltage source coupled to the MDAC and configured to provide a reference voltage to the MDAC. The MDAC comprises a nonlinear calibration circuit configured to adjust an output of the MDAC nonlinearly based on the code, the reference voltage, and an output of the nonlinear calibration circuit.
