Abstract

An electronic device may include digital circuitry to operate via digital signals and analog circuitry to operate via analog signals. The electronic device may also include a fractal digital to analog converter (DAC) to convert a digital signal into an analog signal. The fractal DAC may include a unit cell array having a branching data path and multiple unit cells disposed in a fractal pattern. The fractal DAC may also include multiple decision units disposed within the unit cell array on the branching data path. Each decision unit may receive an incoming signal representative of at least a portion of the digital signal and direct each decision unit output to different branches of the unit cell array. The unit cells may be enabled based at least in part on the decision unit outputs to generate the analog signal.
