Abstract
A circuit arrangement for amplifying a differential voltage signal in an output signal proportional to a voltage difference is provided, the voltages of a signal source that are to be compared being present at two inputs of the circuit arrangement, and a current signal proportional to the voltage difference being present at one output of the circuit arrangement, the circuit arrangement comprising cross-coupled transistors and the inputs being respectively connected to the base of one of the transistors, and a cross current of the circuit arrangement being present at the output. A compensation circuit is provided having a temperature behavior which corresponds to the temperature behavior of cross resistances of the circuit arrangement, the compensation circuit being associated with each of the inputs of the circuit arrangement.
