Abstract
An amplifier output stage that can be operated with low supply voltages and as a voltage amplification greater than one has two complementary transconductance amplifiers having asymmetrical characteristics of their output currents with reference to the input voltages. The amplifier output stage also has two power amplifiers following these transconductance amplifiers and whose outputs are connected to the output node of the amplifier output stage. The amplifier output stage also has a feedback network that is connected between the output node and a reference potential node and defines a feedback node that is connected to respectively one of the inputs of the transconductance amplifiers, whereas the other inputs of the transconductance amplifiers are connected to the input node of the amplifier output stage.
