ABSTRACT:
A system includes a first digital-to-analog converter (DAC), a replica DAC, a control module, and a calibrating DAC. The first DAC receives a first input and generates a first analog output based on the first input. The replica DAC receives the first input and generates a replica analog output based on the first input. The control module generates a first control based on the first input. The calibrating DAC generates a calibration analog output based on the first control. The calibration analog output adjusts the replica analog output.
