Abstract
An electronic device may include digital circuitry that operates via digital signals and a digital to analog converter (DAC) to convert a digital signal into a modulated analog signal. The DAC may include multiple unit cells to generate an analog signal and multiple local oscillator (LO) tiles to modulate the analog signal and generate the modulated analog signal. The electronic device may also include LO circuitry to dynamically adjust an LO enable signal based at least in part on the digital signal. The LO enable signal may enable a reduced number of LO tiles supporting one or more respective sets of unit cells operatively enabled based on the digital signal.
