1. A device including a broadband amplifier circuit, said broadband amplifier circuit comprising at least two field effect transistor stages having a first set of transistors arranged as amplifiers and a second set of transistors arranged as loads, wherein an output signal of a given stage other than a first stage of said at least two field effect transistor stages is fed back to an input of said given stage through a feedback branch which comprises at least one transistor from said second set of transistors of a preceding stage preceding said given stage, wherein said at least one transistor of said preceding stage is double, having a first transistor part entering said feedback branch and a second transistor part providing a load function.
