Abstract
The current disclosure is related to digital-to-analog converters (DACs) with localized frequency multiplication circuits. For example, an electronic device may include a local oscillator (LO) providing clock signals, a digital front-end providing digital signals, a DAC, (e.g., a radio frequency DAC (RFDAC)), and one or more antennas. The DAC may include a number of cells (e.g., unit power amplifiers). Moreover, each cell may provide a unit power analog signal upon activation with a higher frequency than the received digital signals and clock signals. The DAC may provide an output signal (e.g., an analog signal) based on combining (e.g., aggregating) the unit power analog signals of the activated cells for transmission by the one or more antennas.
