Now that we understand how a phototransistor works, we can move forward to understand how an SSR uses the properties of phototransistors and other semiconductor devices having similar working principles like photodiodes, MOSFETs, thyristors, or TRIACs to perform switching in AC and DC loads. ...
Digital radiography systems use active matrix flat panels or linear detector arrays, which consist of a detection layer deposited over an active matrix array of thin film transistors and photodiodes. Digital radiography images are converted to digital data in real-time and are available for analysis ...
In the above section I have explained how to safely connect BJTs in parallel, when it comes to mosfets the conditions become entirely the opposite, and much in favor of these devices. Unlike the BJTs, mosfets do not have the negative temperature coefficient problems, and therefore are free fro...
Very recently, COVID-19 patients have been diagnosed with a particularly insidious condition known as silent hypoxia. Silent hypoxia can do severe damage to the body before any of the typical COVID-19 respiratory symptoms, like shortness of breath, occur. An article on the National Center for ...
A video camera, also called a camcorder, is a portable television camera combined with a video recorder. The camera section has a lens and special charge-coupled device or CCD (a microchip with thousands of tiny light-sensitive elements containing photodiodes). The CCD separates the picture into...
