Optocoupler is an electronic component that has a light source at its input side and a light detector or sensor in its output side. A light source is a LED while the detector or sensor is a phototransistor. It is also called as optoisolator, photocoupler or optical isolator. This device is considered as a current controlled current source. This is
How to bias optocoupler is even simpler than bipolar junction transistors. However such device is not well discussed in the universities making people believe that it is a difficult device to deal with. Here I will reveal the methods and techniques on how to bias optocoupler. Before jumping to the main topic on how to bias optocoupler, let me touch some
