A differential amplifier provides an amplifier circuit including two differential pairs. A first differential pair is connected in series to a second differential pair. The second differential pair is connected in a crosswise manner at least indirectly to a differential output signal of the first differential pair. The first differential pair and the second differential pair form a first differential current path and a second differential current path. A first emulation device is connected in parallel to the first current path. A second emulation device is connected in parallel to the second current path.
