Fractal digital to analog converter systems and methods

A decision unit of a digital to analog converter (DAC), wherein the decision unit comprises:

• an input configured to receive a digital signal comprising a first bit depth, wherein the digital signal is indicative of selective activations of a plurality of unit cells of the DAC;
• a first output configured to output a first decision unit output comprising a second bit depth less than the first bit depth, wherein the first decision unit output is indicative of the selective activations of a first portion of the plurality of unit cells;
• a second output configured to output a second decision unit output comprising a third bit depth less than the first bit depth, wherein the second decision unit output is indicative of the selective activations of a second portion of the plurality of unit cells separate from the first portion of the plurality of unit cells;
• and
• circuitry configured to generate the first decision unit output and the second decision unit output based on the digital signal.

An electronic device comprising:

• digital circuitry configured to generate a digital signal;
• and
• a digital to analog converter (DAC) comprising:
• a unit cell array comprising a plurality of unit cells configured to generate an analog signal in response to selective activations of the plurality of unit cells corresponding to the digital signal, wherein each unit cell of the plurality of unit cells is configured to output a same amount of power in response to activation;
• a data path configured to relay decoded portions of the digital signal to respective unit cells of the plurality of unit cells;
• and
• a plurality of decision units disposed within the unit cell array along the data path and configured to decode the digital signal generating the decoded portions of the digital signal.
