Abstract
Certain aspects of the present disclosure provide apparatus and techniques for segmenting a digital input signal for digital-to-analog conversion. For example, certain aspects provide a segmentation circuit for generating digital signal segments for a digital-to-analog converter. The segmentation circuit generally includes a modulo function logic circuit configured to generate a modulo output signal based on a digital input signal and a divisor input signal and a modulo range extension logic circuit configured to selectively direct the modulo output signal or the divisor input signal to an output of the segmentation circuit. In certain aspects, the output of the segmentation circuit may be used by the digital-to-analog converter to generate an analog signal based on the digital input signal.
