Abstract: An attenuator includes: a first circuit including a common collector or common drain amplifier formed of a first transistor having its control node connected to an input of the attenuator and its emitter or source connected to an intermediate node of the attenuator; and a second circuit including a common collector or common drain amplifier formed of a second transistor having its emitter or source connected to the intermediate node and its control node connected to an output of the attenuator.
