common emitter

Here, I want to use Thevenin with those 2 resistors in the base. How can I combine those two resistors with thevenin or do you have any other better idea to combine them? (circled with red in the picture) (PS: I don't ask the solution of the question. I'm only asking individually the...

I want to study about "finding Input & Output Impedances of Common Emitter BJT Amplifier" However, I could not find a decent source & document about it. Could someone supply me with some documents for that. Then that would be gorgeous for my study. Thanks :)

Hi, I just have solved one of the bjt common emitter question below. However, I'm curious that how can I additionally find those things below: 1) Input and Output Impedance 2) AC Gain Here is the example and my hand draw solution. However, the question only asked to find Vout/Vin... Also, my...

Hi, I want to study about BJT Common Emitter Large (or bias) and Small Amplifier Circuits. My question is I could not find a decent sufficient resource neither from youtube nor from google. :( I want to study about those common emitter large & small signal models, analysis, ac gain, input &...

Hi I'm working on my project about CE amplifier on PSPICE. The circuit given to me is attached below. 1. The first question was 'set bias point'. So what I thought was for DC, capacitor is open circuit. And if we increases V_in, it will cause increase of I_c which will make this transistor...
