Abstract
The present invention refers to a cascode amplifier suitable for amplifying a voltage signal present on the input terminal. The amplifier comprises at least one first transistor comprising a non-drivable input terminal that coincides with the input terminal of the amplifier, a non-drivable output terminal and a drivable terminal connected to a first polarization voltage. The amplifier comprises in addition at least one second transistor comprising a non-drivable input terminal in common with the output terminal of the first transistor, an output terminal non-drivable connected to a second polarization voltage and a drivable terminal. The amplifier also comprises a feedback element placed between the output terminal of the second transistor and the drivable terminal of the first transistor and circuit means coupled between the drivable terminals of the first and of the second transistor and suitable for making the values of voltage on the drivable terminal and on the output terminal of the first transistor substantially the same.
