Abstract
An apparatus for compensating for nonlinearities in a DAC caused by variabilities of a power supply. The apparatus may include a power supply, a processing component, and a front-end circuit. The power supply may generate power, where the power includes variabilities in a power. The processing component may generate a digital signal. The front-end circuit may be operatively coupled to the power supply and the processing component. The front-end circuit may receive the power from the power supply, identify the nonlinearities in the power, receive the digital signal from the processing component, and adjust the digital signal for the nonlinearities to obtain an input signal to send to a digital to analog converter (DAC).
