Abstract
A receiver circuit for receiving and forwarding data signals comprises at least one first and one second input to be used to inject an external digital data signal and a reference signal into the receiver circuit, a multistage input amplifier circuit which comprises a first amplifier stage and a second amplifier stage connected downstream of the first amplifier stage, and a device for actively setting a first operating point of the multistage input amplifier circuit. The multistage input circuit provides the external digital data signal in amplified form at an output and the device generates a bias potential for driving the input multistage amplifier circuit on the basis of the circuit topography of the multistage input amplifier circuit. The bias potential is used to set a second operating point of the first amplifier stage in such a manner that its output signal is within a prescribed third operating point of the second amplifier stage.
