Not only does it describe a model for how transistors really work, it touches on the idea of current flow, which I recently blogged about.Īt any rate, both of these web pages should give you something to chew on today. I’ve only just skimmed this page so far, but what I’ve read I really like. One of the answers points to the web page, “HOW DO TRANSISTORS WORK? – NO, HOW DO THEY REALLY WORK?” by William J. There are other, more complex answers that try to get down to the actual physical workings of a transistor, but I was never much interested in that kind of thing. It’s kind of a simplistic answer, but that’s pretty much how I envision transistors working. Amateur Radio Station Ways to Organize your Ham Radio. These are fed into a transistor that boosts them and powers a tiny loudspeaker, so you hear a much louder version of the sounds. transistor radios Create sophisticated transistor radios that are inexpensive yet highly. A hearing aid has a tiny microphone in it that picks up sounds from the world around you and turns them into fluctuating electric currents. That comes in really useful in things like hearing aids, one of the first things people used transistors for. This receiver can be regarded as a QRP (low power) because the regenerative stage uses some microwatts in order to work. It uses 3 NPN garden type transistors and a LM386 as the audio amplifier. In other words, it’s a kind of current booster. Tropicalized version of the famous 'Desert Ratt', regenerative receiver for SWLs, hobbists, listeners and radio hams. When it works as an amplifier, it takes in a tiny electric current at one end (an input current) and produces a much bigger electric current (an output current) at the other. It can work either as an amplifier or a switch: A transistor is a miniature electronic component that can do two different jobs. A transistor is really simple-and really complex.
