PCT No. PCT/DE95/01150 Sec. 371 Date Feb. 25, 1997 Sec. 102(e) Date Feb. 25, 1997 PCT Filed Aug. 25, 1995 PCT Pub. No. WO96/07084 PCT Pub. Date Mar. 7, 1996A circuit is provided for adjusting an operating point of an opto-electronic element having a saturation voltage and which constitutes a component of a receiver for alternating light useful signals and which generates current during a short-circuit operation and voltage during a no-load operation. The circuit comprises a resistive circuit connected in parallel with the opto-electronic element for adjusting the operating point of the opto-electronic element below the saturation voltage for the compensation of constant light signals. The resistive circuit includes an automatic control resistor which changes its resistance as a function of voltage when a specific voltage below the saturation voltage is exceeded for loading the opto-electronic element until the specific voltage is essentially reached. |
