Abstract :
Experimental and analytical results for a highly linear, temperature insensitive, optocoupler circuit, will be offered, in a feedback arrangement, one GaP LED shines equally on two photodetecting diodes. Photon current generated from one detector is used for feedback control of nonlinear and temperature-sensitive LED light generator, while light-generated current in other diode equals that of first diode. Arrangement affords mass fabrication.
