Current digital-to-analog converter with distributed reconstruction filtering

A digital-to-analog converter providing distributed reconstruction filtering, the digital-to-analog converter comprising:

• a bias circuit configured to provide a first predetermined voltage level as a first output of the bias circuit, a second predetermined voltage level as a second output of the bias circuit, or a transitioning voltage level as a third output of the bias circuit, the transitioning voltage level linearly transitioning from the first predetermined voltage level to the second predetermined voltage level over a predetermined number of periods of a clock signal having a first frequency;
• a plurality of digital-to-analog current elements configured to generate a plurality of currents, each current of the plurality of currents being generated by a corresponding digital-to-analog current element of the plurality of digital-to-analog current elements according to a corresponding control signal of a plurality of control signals;
• a combiner circuit configured to combine the plurality of currents to generate an output current;
• and
• a decoder circuit configured to determine next states of the plurality of digital-to-analog current elements based on a digital code received synchronously to the clock signal and to generate the plurality of control signals based on the next states of the plurality of digital-to-analog current elements, each control signal of the plurality of control signals selecting the first predetermined voltage level, the second predetermined voltage level, or the transitioning voltage level for use by the corresponding digital-to-analog current element.
