Abstract
A high frequency amplifier circuit arrangement has an output current path having one end coupled to a reference potential for supplying an alternating signal current at an output terminal. The influence of parasitic inductances in the output current path on the amplitude of the alternating signal current is reduced or cancelled in that compensation is provided for the influence of a parasitic inductance in the coupling between the output current path and the reference potential by means of a compensation circuit which applies an alternating compensation current to a (first) node between the output current path and the parasitic inductance. This compensation current is in phase opposition to and of at least substantially the same magnitude as the alternating signal current.
