Abstract
A broadband amplifier comprises a bipolar transistor (T), having a base connected to the input terminal (2), a collector connected to the output terminal (3) which is in turn connected to a supply source (11) through a first resistor (R1), and an emitter grounded. A second resistor (R2), the value of which varies simultaneously with the current gain (.beta.) of the transistor is connected between the output terminal and the transistor base. This broadband amplifier further comprises a capacitor (C) connected in parallel across the terminals of the second resistor and a third resistor (R3) connected between the second resistor and the transistor base.
