Abstract
Integrated circuit arrangement including a differential amplifier (1) whose outputs are coupled to a load resist arrangement (5, 7) and to a transistor (6, 8) arranged as an impedance transformer, and whose control input is coupled to a current source (4). The outputs of the differential amplifier are coupled to the outputs of a compensation differential amplifier (15). The inputs of the compensation differential amplifier are coupled to a first reference potential and the control input of the compensation differential amplifier is coupled to a second reference potential. Furthermore, a resistor arrangement (21) is coupled either to the inputs or to the control input of the compensation differential amplifier.
