My understanding, please correct me if I am incorrect, that the current gain of a Darlington is at its most linear *IF* there is no voltage swing from Collector to Emitter, so that the output is just collector current - no voltage swing on the Collector. Just current in, just current out. The DC voltage on the Collector stay in effect DC.
The mobile charge carriers consists of electron flow that's opposite the sign convention for current flow. This recognition is needed to relate the current to the doped silicon crystal structure in the form of n-type and p-type
Why does this daisy chain configuration of bjt have to stop with only 2 bjts? It seems as though a 3rd bjt could be driven as well for even higher gain
does In transistor. output should be taken across emitter terminal .is that the reason why we are considering out current across emitter terminal(ie2)?
HELLO THERE . THERES A TIP142 NPN TRANSISTOR IM TRYING TO USE IN MY ONE TRANSISTOR SOUND AMP . SO TELL ME WHERE IS THE EXIT IS IT AN EMITTER OR COLLECTOR ???
ie1 is appropriate in mili amps and the base current should be in microampers how you are giving ie1 directly to ib2 ??? how the second transistors is working safely???
what happened to the input impedance and output impedance values in darlington pair and sir will u please give me a link to download its ac analysis here ?
base-emitter voltage is 0.7 for silicon. If you remember the input characteristics, if this voltage increases, diode will require more voltage in order to start operating.
Ideally 0.7V for it to remain in an active condition, factoring temperature and current thorough the BJT in real life is different though. Hmm, i guess other viewers who asks the same question as this should explore more about operation conditions. The graph or characteristic curves will tell you about it.
If you still don't get it. JUST FORGET IT. Think about Vbe as constant 0.7V in DC analysis on FB silicon. Explore more about this when you finished electronics. As ideal and full models confuses a lot of students in their first electronics subj because they overthink.
Note that the total current gain of a Darlington pair is actually β=β1*β2+β1+β2. We usually neglect (β1+β2) because it is much smaller than (β1*β2).
Thank you very much for your explanation
You are the best lecturer ever!
Inglis
Me To My Wife After 6 Hours' Session With Neso Academy: "We're Darlington Pair🥳"
That was REALLY good 😉 "Thank You", thank you very much for your presentation 😎
Sir, your lecture is so helpful.
Again here after 7 years last
I used to watch your videos during summer 2017 to Feb 2018

sir plzz upload lecture on power amplifiers and their classes
Watch lectures of adigo edutech channel. They have explained it there.
Thanks for the video. Was very helpful.
sir 0ne of the great lecture .. thanks sir

Messed around and overheated.. my Zeus Amp!!! -- e40 //The original Zeus Amp had 36 Darlingtons. I was amazed..
Very useful lecture completely clear now thank you
Sir plss upload some videos of feedback amplifier
sir can i use this circuit for potential divider biasing? with base emitter voltage of 0.7+0.7 =1.4 volts?
Where are the notes of AC analysis of Darlington pair,?
If I use two Bc547 transistors as Darlington pair, will it double the current?
sir,please upload lectures on opamps & multivibrators using opamp
Sir how to solve more complex circuit in which we are using one transistor and two MOSFET
Simply for current gain multiply and divide by ie1 yu will get desired result
great video, learnt a lot from this:)
Is there a lecture on differential amplifiers using discrete transistors?
Can BC547 and 2N2222 BE added to form a darlington pair with pull up resistances
thank you sir ...very nice explanation
Thank you for providing us such a us video.
Thank you!
Why does this daisy chain configuration of bjt have to stop with only 2 bjts? It seems as though a 3rd bjt could be driven as well for even higher gain
Thank you sir❤
How do we connect 4 BJT (TIP41C) in DARLINGTON circuit ??
I understood how to do it for 2 BJTs.
does In transistor. output should be taken across emitter terminal .is that the reason why we are considering out current across emitter terminal(ie2)?
Make a lecture of feedback connection and types
Sir, Can we amplify the current more by adding another transistor?
and Please upload some lectures on FET's.
Can you please, upload RC coupled amplifier explanation..
Thank you
Thank you sir
can you add a lecture for ac equivalent ckt for darlington ckt and calculate all the respective parameters
Sir can you do lectures on opamps?
Plz calculate also the value of ic of transistor 1st and 2nd individual
Sir can you please Tell Overall Transconductance of this Darlington pair??
Sir how should we find this ckt zo,zi, AV??
Darlington BJT vs. MOSFET current capabilities? (FWIW, Darlington vs. Sziklai?)
HELLO THERE . THERES A TIP142 NPN TRANSISTOR IM TRYING TO USE IN MY ONE TRANSISTOR SOUND AMP . SO TELL ME WHERE IS THE EXIT IS IT AN EMITTER OR COLLECTOR ???
"Thank You", thank you very much 😀 That was REALLY Really really good 😎😋😎
Can you guys explain the h-parameter model of the same darlingtonamp
Sir great explanation words just copied in mind
ie1 is appropriate in mili amps and the base current should be in microampers how you are giving ie1 directly to ib2 ???
how the second transistors is working safely???
I need feedback amplifier and oscillator
how much voltage drop is dralinton transistor
sir, thank you
Plz explain... Why in voltage stabilizer there is need to use darlington pair?
pls make a video about transformer coupling too.
Nice.carry on.
Awesome I got it know from edupoint
what happened to the input impedance and output impedance values in darlington pair and sir will u please give me a link to download its ac analysis here ?
Sir pls tell ac analysis also na
thanks sir
Sir please upload Darlington pair ac analysis
Why shouldn't the base-emitter voltage be high?
Sir i find some difficulty to make the equivalent circuit or transistor pair
Where are the notes of Darlington AC analysis ????
what happens when Q2 is PNP?
oh this is good thing
sir 10q it is clear
How to over come by mill ampere to Ampere
👌👌👌
How to find Zo, Zi, Av
why Bd is not = B1+B2 even Vbe = Vbe1 + Vbe2
Sir, why don't we want base-emitter voltage to be large?
same question..

i need differential amplifier
sir,what is the problem when base -emitter voltage is high?
when the Vbe is high transistor will require more amount of supply vtg to conduct.
sir plz upload op amp part
Where is the analysis of Darlington
ur web sit???
can you make it more easy?
Sir I want a help plz reply asap
?
👌
Super beta topic was not said
