Patent ID: 7372331

Claim:
A receiver circuit for receiving and forwarding data signals, comprising: at least one first and one second input to be used to inject an external digital data signal and a reference signal into said receiver circuit; a multistage input amplifier circuit which comprises a first amplifier stage and a second amplifier stage connected downstream of said first amplifier stage; said multistage input circuit providing said external digital data signal in amplified form at an output; and a device for actively setting a first operating point of said multistage input amplifier circuit; said device generating a bias potential for driving said multistage input amplifier circuit on the basis of the circuit topography of said multistage input amplifier circuit; said bias potential being used to set a second operating point of said first amplifier stage in such a manner that its output signal is within a prescribed third operating point of said second amplifier stage, said device comprising a regulating circuit, the regulating circuit comprising a feedback path comprising said first replica of said second amplifier stage and a DC voltage potential whose value is a measure of the switching instant of said second amplifier stage being fed to an input of said first replica.
