Abstract
An amplifier circuit is disclosed having an output transistor for driving a complex load over a drive frequency range, wherein in the lower part of the range an inductive component of the load dominates and in the upper part the inductive component does not dominate. The amplifier circuit includes a current mirror circuit that is connected upstream of the output transistor and has a shunt path to a second potential, for the purpose of relatively reducing a DC current flowing through the output transistor in comparison with an AC current flowing through the latter.
