KOPPLINGSANORDNING FOER EN OPTOELEKTRISK TRANSFORMATOR

摘要

A circuit arrangement is specified by means of which an opto/electrical transducer, which has a transimpedance amplifier (2), can be operated independently of the intensity of the incoming light pulses without there being a risk of overdriving the transimpedance amplifier. For this purpose, the input current is limited by means of a voltage-dependent electrical element (9) having a low threshold voltage.
