ABSTRACT:
A radiofrequency amplifier device includes a transconductor stage having an input for receiving a radiofrequency signal, and a cascode stage connected to the output of the transconductor stage. The device also includes an auxiliary radiofrequency amplifier compensation stage connected as a negative-feedback loop between the output of the transconductor stage and the base or the gate of the cascode stage.
