KREDSLOEB TIL FOROEGELSE AF DYNAMIKOMRAADET I EN INTEGRERENDE OPTOELEKTRISK MODTAGER

摘要

A circuit for increasing the dynamic range in an integrated input stage in an optoelectric receiver comprises a feedback F2 between the output from an amplifier F1 in the stage and the pole of an optoelectric transducer D which faces away from the input of the amplifier F1. The amplification of the feedback can be controlled dependent upon the light intensity, using a generator G connected in series with the transducer D.
