Actually, Optocoupler circuit design is not that difficult as some thought. It’s just like you are designing a BJT circuit.
How to bias optocoupler is even simpler than bipolar junction transistors. However such device is not well discussed in the universitiesContinue reading
Current transfer ratio is comparable to BJT’s HFE or beta (β). This is the ratio of the optocoupler’s collector currentContinue reading
Opto coupler CTR explanation is not well elaborated by other authors and before I was also having hard time ofContinue reading
One of the usual applications of optocoupler is to provide isolation between two ground reference. That is why it isContinue reading
