Abstract:
Certain aspects of the present disclosure generally relate to circuitry and techniques for digital-to-analog conversion. For example, certain aspects provide an apparatus for digital-to-analog conversion. The apparatus generally includes a mixing-mode digital-to-analog converter (DAC), a duty cycle adjustment circuit having an input coupled to an input clock node and having an output coupled to a clock input of the mixing-mode DAC, and a current comparison circuit having inputs coupled to outputs of the mixing-mode DAC and having an output coupled to a control input of the duty cycle adjustment circuit.
