Vishay Intertechnology has introduced two 850-nm and 940-nm infrared emitters and a package-matched silicon PIN photodiode with high radiant sensitivity from 780 nm to 1050 nm for use in infrared ...

Optical systems have many unique attributes that make them useful for range detection and communications, but often the optical signal needs to be converted to an electrical signal as part of the ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...
