Abstract:
1. An amplifier coupling, comprising a first, a second, a third and a fourth transistor, additionally comprising a signal input port and a signal output port, wherein the input port of the amplifier is connected to the first, second, third and fourth transistors such that an input signal to the amplifier is input to the first and the fourth transistor in parallel and to the second and third transistors in parallel, with the outputs from the first and second transistors being connected to each other at a first output common point, and the outputs from the fourth and third transistors being connected with each other at a second common output point, said first and second common output points being connected to each other to form the output port of the amplifier; wherein the inputs to the first and fourth transistors are from a first common input point in the amplifier, said first common input point being connected to a second common input point from which the input signal is input to the second and third transistors.
