Abstract
Certain aspects of the present disclosure generally relate to a programmable multi-mode digital-to-analog converter (DAC) for generating a frequency-modulated signal. For example, certain aspects provide a circuit for sweeping a frequency of an output signal. The circuit generally includes a DAC having an input coupled to an input path of the circuit and an output coupled to an output path of the circuit, a first mixer selectively incorporated in the input path coupled to the input of the DAC, and a second mixer selectively incorporated in the output path coupled to the output of the DAC.
