Patent ID: 7224229

Claim:
An electronic signal amplifier comprising: a power source having a first and a second terminal; an input inductor and an output inductor each having a first and a second end terminal and a given number N of intermediate terminals, where N is an integer greater than or equal to unity, said first end terminal of the input inductor and said second end terminal of the output inductor being respectively connected to an input and to an output of said amplifier, and said second end terminal of the input inductor and said first end terminal of the output inductor being connected to said first terminal of the power source; and N branches connected in parallel between said first and second terminals of the power source, each branch comprising: a capacitor; and a transistor having a control electrode having a connection to a respective intermediate terminal of the input inductor, the connection to the intermediate terminal of the input inductor bypassing the end terminals of the input inductor, a first main electrode connected to said first terminal of the power source, and a second main electrode connected to said second terminal of the power source via said capacitor of said branch, said second main electrode of said transistor having a connection to an intermediate terminal of the output inductor, the connection to the intermediate terminal of the output inductor bypassing the end terminals of the output inductor, an internal capacitance existing between the control electrode and said first main electrode of said transistor.
