An amplifier circuit has a first transistor and a second transistor of a first conductivity type, which are operated in a cascode circuit together with a first resistor. In addition, the amplifier circuit includes a first capacitor, which precedes the control input of the first transistor. A third transistor of a second conductivity type is provided, whose control input is connected to one end of the controlled path of the second transistor and whose controlled path is connected on one end to a second supply potential. A fourth transistor of the second conductivity type is provided, whose control input is connected to the other end of the controlled path of the third transistor and whose controlled path is connected on one end to the control input of the third transistor. A second resistor is connected between the control input of the fourth transistor and one terminal of the first capacitor. Finally, a third resistor is connected between the other end of the controlled path of the fourth transistor and the other terminal of the first capacitor.
