Abstract
An amplifier stage includes a first and a second signal path having a series connection of a first transistor of a first conduction type which forms a control input for receiving an input signal to the amplifier stage and a second transistor of a second conduction type. The amplifier stage further includes a first and second signal output which are formed by a respective connection node of the respective first and second transistors. For each of the first and the second signal path, the amplifier stage includes a third transistor of the second conduction type which is connected to the respective second transistor as current mirror, and a fourth transistor of the first conduction type which is connected to the respective first transistor as a current mirror and which is for controlling the third transistor of the other signal path, respectively. Furthermore, for each of the first and the second signal path, a current source is provided with is connected in parallel to one of the respective first, second, third, and fourth transistors.
