Amazing explanation👍 Why common emitter and common collector amplifiers are called like this? Cannot understand how are they common to input and output signal 🤯
Are you are taking the Vocademy course? If so, it is covered in the section Analog Circuits under Amplifiers. If not, Google Vocademy, go to his website and sign up for the electronics course. It's free and presents all of his TH-cam videos along with more information. Easiest thing to remember with transistor amplifier types is to ask the question "Where is the output?". If the output is the collector it is a common collector amplifier. If the output is the emitter it is a common emitter amplifier.
In any transistor amplifier circuit, each terminal is tied either to input, output or "ground". In the circuit shown (common emitter) the input is between base and ground, the output is between collector and ground, and the emitter is tied straight to ground. Thus, both the input and output signals go through the emitter, so it is "common" to both. In a common collector circuit, the input is between base and ground, the output is between emitter and ground and the collector is tied to ground (through the power supply). Thus, both the input and output signals go through the collector (after the power supply), so it is common to both.
Great explanation. Thank you so much sir for teaching us such interesting things.
❤❤❤
Nice 👍👍
Very interesting. Thank you. I wish you good luck
