Abstract
An electronic system (10) is formed to include a circuit (11) having a digital-to-analog converter (12). Digital-to-analog converter (12) is formed to add an error voltage to the digital-to-analog converter output to adjust or translate the analog output value to include a power return offset value.

A method of forming a semiconductor device comprising:
- forming a digital-to-analog converter circuit of the semiconductor device to include a digital-to-analog conversion network coupled to convert a digital input into an analog signal having a first value at an output of the digital-to-analog conversion network;
- forming a translation circuit coupled to translate the first value to a second value that includes a power return offset value;
- and
- coupling the translation circuit to apply the second value to the output of the digital-to-analog conversion network.
