Undergrad Why do the free electrons in the N-type want to diffuse?
I'm trying to understand how a diode works and for this I've used(among other resources) the book written by Albert Malvino, Electronic Principles. Everywhere I read about this topic, it says that when the N-type and P-type semiconductors are joined together, the free electrons from the N-type...- SaruMihai

Common Emitter Amplifier Analysis
But beside the wrong calculated Gain,the rest of the analysis is right for q active point calculation? And I found on the internet that Rb < βRe so that Re feedback to work which means that VRb < VRe assuming that Ic ≈ Ie,could anyone please tell me why?- SaruMihai

Common Emitter Amplifier Analysis
This is my analysis of common emitter amplifier. Ic = βIb Ic ≈ Ie (because Ib is very small) => Ie = βIb Vcc = IcRc + Vce + IeRe Vcc = IeRc + Vce + IeRe Vce = Vcc - βIb(Rc + Re) Vb = IbRb + Vbe + IeRe Vb = Ib(Rb + βRe) + Vbe Gain = Vce/Vb Gain = (Vcc - βIb(Rc + Re))/(Ib(Rb + βRe)...- SaruMihai
