A receiver circuit having an optical reception device and having an
amplifier connected to the reception device, the amplifier also having a
circuit for setting the operating point of the amplifier and also at
least one control terminal of the circuit, by which the operating point
of the amplifier can be selectively changed between at least two values
at the user end. The receiver circuit according to the invention enables
a noise optimization of the amplifier by virtue of an adjustability of
the operating point of the amplifier.
