Abstract

A system includes an N bit sub-binary radix digital-to-analog converter (DAC) that converts an m bit digital input signal to an analog output signal, where m and N are integers greater than or equal to 1 and N>m. A radix conversion module determines a code ratio, the code ratio being a ratio of a total number of available monotonic codes to 2m, and performs radix conversion on the m bit digital input signal based on the code ratio.
