Example embodiments of the invention may provide for active baluns. An example active balun may include a resonator that may convert a single-ended input signal to at least two differential input signals, and a differential switching block that includes first and second transistors that each receive a respective one of the at least two differential input signals from the resonator, where the first and second transistors may be cross-coupled to each other to provide a first differential output signal and a second differential output signal. An example active balun may further include one or more loads connected to the first and second differential output signals, and one or more stacked inverters that may provide a first output port and a second output port, where the first output port may be responsive to the first differential output signal and the second output port may be responsive to the second differential output signal.
