Abstract
The present document discloses circuits and methods for providing an output voltage at an output port. In one of the embodiments, a circuit has a power amplifier having an output. In particular, the circuit may have a first transformer including a first coil and a second coil. Moreover, the circuit may have a first capacitor connected in parallel to the first coil and a second capacitor connected in parallel to the second coil. More particularly, the circuit may be adapted to have a first end of the first coil connected to the output of the power amplifier, and a second end of the first coil connected to the output port of the circuit.
