ABSTRACT:
An amplifier arrangement having a first and a second output transistor, which are drain-connected to the output terminal. A driver stage (100), prevents the output transistors from becoming non-conductive, thereby reducing cross-over distortion. This is achieved by applying an input signal via the sources of a source coupled transistor pair to the gates of the output transistors. Additional source followers are provided for defining gate-sources voltages which prevent the output transistors from becoming non-conductive.
