how do you know so much?? I've been watching your videos since I was in high school and now I'm in my third year of engineering and your content is still saving my life.
Good into to basic amp configurations. There are situations where gain is not sought after, but linear response and a means to regulate input to an IC chip. Analog devices may use a 10v supply and a chip can't use 0-10v, but needs 0-2v and the amp design exists to faithfully rescale that devices output. I think automotive MAF sensors need this? Drop the I/O capacitors, and the appication becomes dc-dc, but... which configuration is best?
I don't understand why you would want your alternating current source to send a current to the collector supply voltage.Good discussion at the end comparing everything.
kinda understand the vid, its just that I'm confused to why is the output sometimes at the emitter or collector. I studied the concept of transistor and fromw hat I understand the output should only be at the collector but why is that the output sometimes at the emitter? pls help I'm very confused
@TheOrganicChemistryTutor Tutor you mentioned that the C.C config gives high power gain due to high Zin and low Zout, and thats what we want. But you concluded the video showing we get the highest power gain in the C.E config???
the problem with this analysis is that you're not explaining WHY you might use each of these amplifiers - and that's just as important as how they work for an engineer. At first look, a Common Base amp seems pointless - it has low i/p impedance , high o/p impedance and no current gain - seemingly the EXACT opposite of the ideal amplifier. From the description it would appear that the better option where would be a common emitter amp - because you get voltage gain, current gain and you have high i/p and low o/p impedance... BUT - the Common Base amplifier has very low 'miller capacitance' effect, which means that it's exceptionally good in high frequency situations. By comparison the common-emitter amplifier miller capacitance effect will render your voltage gain useless at high frequency...
It's actually called a "voltage divider" amplifier because of the 2 base resistors forming a voltage divider. I don't know who told you it's called a common emitter, but they're wrong. Yes, the emitter is common, but the correct name for this configuration is voltage divider.
The voltage devision is mainly for biasing the transistor thus we refer to the circuit as common emitter, reason being the emitter is the common terminal meaning that neither the input nor the output is at that terminal.

You are a legend man! You know everything! Electronics, Chemistry, Math, Physics, anything. You are the STEM wizard.

I’ve been watching your videos since 2 am, now it’s 6.30 am. I’ve been doing your maths. You made me realize maths is like a drug!
Amazing😯😯😯

Stay safe out there, Tutor. ♥️
Best tutorial on organic chemistry ever!
Woooaww. One of the most straightforward (straight to the point) amplifier class explanation. Thank you v. much.
Wow, you’re really amping up the educational content on UA-cam. Keep it up!
So nice explanation my best teacher
Stay safe tutor always good video
Pray for the world especially for those COVID-19 victims.
Thank you! Hoping you'd also tackle the FET topic.
May you please post a video on how to do the AC calculations
Thank you.
We need to see the face of this legend
Man ! I love your voice
with the CB, whats the difference between using voltage dividers and -Vee?
Will you upload quantum chemistry videos someday?

Is common emitter less stable than common collector?

Same doubt
Great content
I am hoping you’re coping with this Covid-19 situation. Stay healthy, our great tutor❤️
I think the cicuit you drrew for common collector was of common emitter
What do you mean by "theoretical power gain"? How do we know its value?
THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!
Voltage gain is high for common base, input impedance is low and output impedance is high
I'm studying the iscet test. on the practice exam it states that the gain of the common collector (emitter follower) is approx.. 1
Can you also make a video about the COVID-19? I think, people will really love you to do that. God bless.
Best of Highlights I agree, because he knows chemistry
Right. I dont know why he doesnt want to do that.
Thank you

I believe it’s that cc gives higher voltage gain but a lower power gain than ce
Takes me back to 8th grade
Cc amp can be a buffer
How about 2 stage amplifier for a project.
