    Thevenin's theorem BJT derivation

    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...

    Input and Output Impedance of the Common Emitter Amplifier

    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...

    BJT Common Emitter Large and Small Signal Research

    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 &...

    Project about CE amplifier on PSPICE

    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...
