Abstract
A system includes a sub-binary radix digital-to-analog converter (DAC) that converts a digital input signal to an analog output signal based on a sub-radix DAC code. A radix conversion module performs radix conversion on the digital input signal. To perform the radix conversion, the radix conversion module associates bit positions corresponding to the digital input signal with respective analog weights and converts the digital input signal to the sub-radix DAC code based on the respective analog weights.
