Emitter-Follower Configuration (Part 1)

[@juliocesarmamaniccanihua6561]

what kind of board do you use to write? It is the best electronic video that I have seen

[@RiaziMohandesi]

Wacom

[@myprogrammingbuddy153]

Including value of ro makes the final equations complicated and in most situation ro effect can be ignored. So ro is considered infinity

[@rajgandhi4042]

Sir you have mentioned that in other Bias circuit Input impedence is low and Output impedence is High HOW?

[@piyushthakur7960]

thnku sir ... ur all video is too useful for me 👈🙏🙏

[@HRIEDITZ]

Can we do collector terminal to gorund it wil be also correct?

[@sbybill3271]

I didn't understand output resistance ro. Where do you get it from and what does it represent? Is it specified in the datasheet? Is it always very high?

[@vamsikrishna5391]

sir when u applied kvl to base emitter loop u took Vbe=0.7 but we r doing ac analysis y we r taking that junction voltage also.In previous Re models u just took dynamic resistance n u have not taken this junction voltage but here u r taking y?

missing he sir yahna se kuchh

[@Hope-ur-having-a-wonderful-day]

Youre a legend

[@YousifAhmed-m8y]

0:18 How is this circuit is common emitter ? here we have the base as input and emitter as output and collector is connected to ground so this circuit must be common collector .

[@lxkakkarot3689]

Isn't it common collector ? , you are saying its common emitter in the video ??

[@anjanisingh1452]

vaibhav sahai

[@sexo6162]

Can also be considered as common collector

[@Hunar1997]

But why, i dont see the collector being common

[@collegetv7986]

collector gets grounded in ac equivalent so it is common collector

[@Hunar1997]

So that is how we determine it :/ why books dont say it like that

[@Shiva-jg7zy]

Sir how to get 180 deg phase shift at collector terminals

[@akbarbadshah9248]

Hai sir, in CE amplifier emitter is grounded because it act's both input and output port.similarly in CB amlifier base is grounded.But CC amplifier as shown in above video no collector terminal is grounded,then how it act's as CC amplifier.

[@GauravGupta-pb8mk]

Thank you sir

[@souravjha2146]

WHO design intro song of this channel…it kind of catchy

[@treasuretotrash2067]

Probably a Kevin Macleod song

[@akbarbadshah9248]

sir,please reply.and the next dout is current always prefers low resistive path.if there is no resistance in collector terminal then all the current from Vcc will flow through collector terminal only,it will not enter the base resistance.

[@umairfarooq3160]

thank u soo much sir. this helped me alot. sir upload lecture on darlington pair also

[@senjutipodder5524]

Please upload RC coupled amplier

[@cpavithra8880]

Please post the video for transformer coupled emitter follower amplifier

[@thirupathimaddi435]

Explain about common collector amplifier

[@devanaboinajayaprakash4316]

What is the use of capacitors C1 and c2

[@PRAVEEN_RAJ.]

Both are coupling capacitor C1=> will block the input DC voltage which coming from the source C2 =>Will block the DC voltage which coming from the amplifire circute

[@zizo-ve8ib]

At 5:30 how did u reach that Zi ↑ & Zo ↓ Sir ?

[@babulaswain9744]

Sir why dont u use r0 like in previous re model???

[@MATHEMATICSBYNITianHimanshu]

tq sir

[@unclebens5286]

I wonder why the resistor at the base emitter junction is (beta+1)*re? Could u pls explain this?

[@vedagayathrisalla]

REFER Re model of transistor

[@darshanvs6446]

(beta+1) is nearly equals to beta so he written like that . this approximate re model.

[@jahansaid6382]

What happened to RO ? you didn't include it on your circuit model

[@abhishekverma2568]

Who did the Hw

[@parthanayak1620]

can anyone please say me that in 6:03 time sir said that we will short circuit the DC sources which is Vcc, then the capacitor . But the capacitors are used for blocking the dc signals and easily pass the ac signal . But here sir is saying to obtain the AC circuit ,short circuit the dc sources which are Vcc, capacitors ... How? please reply

[@erdoganyildiz2596]

Why didn't we put ro next to the dependent current source at re model?

[@jahansaid6382]

Did you figure it out, why he din not add ro ?

[@raghuramposina4274]

Explain about source follwer..

[@tusharikas5447]

emitter follower is cc config..but is the ckt correct?

[@sathvikeve-0176]

Sir i didn't understood how is Vi=Vo?

[@urmilapathivada2046]

Can anyone tell me what type of negative feedback is present In emitter follower. Voltage series or voltage shunt!!?

[@sohailahmedsheikh5345]

Voltage series

[@sreedevimohan4701]

Where did r0 go it should be there in re model ..!y didn't u consider

[@quicknaturalbeauty]

If voltage gain is unity then why it is connected in circuit???

[@zynthos9]

This is common collector right?

[@EdwinFairchild]

common emitter, look at what side is connected to ground (common ground) so since emitter is connected to ground this is a common emitter

[@zynthos9]

Eddie Amaya But the output is on the emitter side, which is what I though determined that? And the collector is connected directly to the VCC rail?

[@EdwinFairchild]

1 opps, im a wrong , you are correct it is common collector

[@singkreality3041]

It seems sir don't understand what is ro and how to implement it.

[@kettelenegaspard685]

What would be the voltage for a class a amplifier

[@thirupathimaddi435]

Why we have 2 take re at resistor session

[@mahmudulhasan672]

isn't it a common collecter configuration??

[@morbido13]

Emitter follower is the same as common collector

[@dhanushh2171]

units are not clearly explained and continuity is not clear

[@syeedakudhsiafatima1430]

osssuuumm?!!!
