Abstract:

Systems and methods for operating a digital-to-analog converter (DAC) are described. In an example, a device can receive a digital input. The device can generate a clock signal having frequency in radio frequency (RF) range. The device can combine the digital input with the clock signal to generate a first voltage signal. The device can convert the first voltage signal into a second voltage signal having at least two phases. The device can convert the second voltage signal into a current signal. The device can distribute the current signal to at least one current mode DAC.
