Small Signal Amplifier Circuit Using Transistor
We are going to learn how to design a small signal amplifier circuit using transistors in a simple way, with class A amplifier form. Read more
Preamplifiers
Experiment with adjustable transistor circuits partially on-off
In the previous articles, we learned about using a transistor as a switch, that was, either completely on or off. But circuits such as the audio amplifiers will require the transistor to be partially on, which is very interesting. But it can be quite a difficult subject for beginners who just started learning electronics to … Read more
