Abstract
A power digital to analog converter may include a course-resolution digital to analog converter for converting a first segment of binary digits into a first analog output having a first voltage. The power digital to analog converter may also include a fine-resolution digital to analog converter connected in series with the course-resolution digital to analog converter. The fine-resolution digital to analog converter may be configured for converting a second segment of binary digits into a second analog output having a second voltage. The first voltage and the second voltage may be added together to produce an analog output signal representing the binary digits.
