Abstract:
1. An amplifying device arranged to receive an input signal having a certain duty cycle, said amplifying device comprising: a first switching unit having an input terminal adapted to receive a first half of the input signal, and an output terminal adapted to be connected to a first signal output where a first half of an output signal is provided, a second switching unit having an input terminal adapted to receive a second half of the input signal and an output terminal adapted to be connected to a second signal output where a second half of the output signal is provided, the amplifying device being characterized by: the first switching unit and the second switching unit being adapted to receive an input signal, wherein the first half of said input signal has the same duty cycle as the second half of the input signal but shifted in phase, and said amplifying device further comprises: a first reactive element having a first terminal and a second terminal, wherein the first terminal of the first reactive element is directly connected to the output terminal of the first switching unit and the second terminal of the first reactive element is directly connected to the output terminal of the second switching unit.
