Abstract
A digital-to-analog converter (DAC) capable of operating in radio frequency (RF) with linear output, low distortion, low power consumption, and input data independence. The DAC includes switch drivers and output switches driven by the switch drivers. The switch drivers include pairs of outputs, and positive feedback circuitries coupled between respective pairs of outputs. The output switches are arranged between a first current source configured to push current to the DAC's outputs and a second current source configured to pull current from the DAC's outputs. Different output switches are configured to push current to and pull current from the DAC's outputs in accordance with rising edges and falling edges, respectively.
