ABSTRACT:
An optical receiver comprises a plurality of sequentially-connected, symmetrically-constructed operational amplifiers having two complementary outputs. For the determination of the operating points and for suppressing the offset voltages, one output of each amplifier is connected by way of a negative feedback path to the second input of the first amplifier, whereas the useful signal is supplied to the first input of the first amplifier.
