ABSTRACT:
An embodiment of an electronic signal amplifier comprises a power source, an input inductor, an output inductor and one or more branches connected in parallel between the terminals of the power source. Each branch comprises a transistor having a control electrode connected to an intermediate terminal of the input inductor, a first main electrode connected to a first terminal of the power source, and a second main electrode connected to a second terminal of the power source via a capacitor. The second main electrode of each transistor of a branch is also connected to an intermediate terminal of the output inductor.
