The most common application of Optocoupler is signal isolation. It provides complete isolation because its input side is not electrically
Continue readingIn optocoupler, CTR stands for current transfer ratio. This is comparable to the current gain beta in BJT. This is
Continue readingWhen you already heard about Optocoupler devices, you may be heard also about CTR. CTR stands for current transfer ratio.
Continue readingThe optocoupler operation as switch is similar on how to configure BJT as switch. For a BJT to operate as
Continue readingThere are several ways on how to determine Optocoupler operation. The old school method is to build an actual circuit
Continue readingActually, Optocoupler circuit design is not that difficult as some thought. It’s just like you are designing a BJT circuit.
Continue readingHow to bias optocoupler is even simpler than bipolar junction transistors. However such device is not well discussed in the universities
Continue readingCurrent transfer ratio is comparable to BJT’s HFE or beta (β). This is the ratio of the optocoupler’s collector current
Continue readingOpto coupler CTR explanation is not well elaborated by other authors and before I was also having hard time of
Continue readingOne of the usual applications of optocoupler is to provide isolation between two ground reference. That is why it is
