Abstract
A differential amplifier includes two channels. Each channel has an input, an output, an emitter transistor, and a first current source. The channels are connected to one another via a resistor. In at least one of the two channels, a potential-shifting device is assigned to the first current source. A voltage-controlled, second current source is provided for linearization purposes. A third current source forms the output of the differential amplifier.
