Common-Base Configuration of a Transistor

[@simranbharatgadkari]

Passing my ECCF exams only because of you, sir! Thanks a lot :)

[@AmanKumar-wh8tk]

Thank u, twas really conceptual and eliminating out confusions. I liked the way, you drew Vcb and Vbe later in the circuit and gave understanding of its terminals. Most of the lectures i found previously, they seemed to mug up the circuit diagram without and explanations and then explain just the results, that too in a confusing way.

[@willwill9035]

The best of the best!!! This video is simple yet knowledgeable; and the teacher gives you some valuable information that most other teachers neglected to mention.

[@npstock1489]

Thank you for uploading videos with such clear explanations. It's a kind request to you sir that please upload practicals on electronics like digital gates using IC's.

[@sanskritachakraborty7484]

Excellent lecture! Thank you sir for the conceptual clarity😄

[@RakibulIslam-ez2yr]

in vk mehta book, nomenclature of Vbe is opposite , it confused me and i opened this lecture to clear my confusion , my confusion is now totally clear ! Thank you so much Sir ! greetings from Bangladesh

[@SAISRIVIDYA66]

Sir. We r fortunate to have ur lectures seriously... Thanks a lot. Sir y emitter should be highly doped as well as base is lightly.? What's d reason behind it. Plz tell me sir.

[@313Ritesh]

Base is lightly doped so that there is less recombination in it and more charge carriers are able to pass to the collector region. The emitter is highly doped to get large number of charge carriers in forward bias.

[@SAISRIVIDYA66]

tq sir

[@manamvijayachandra3705]

Emitter is heavily doped as it's job is to produce much number of electrons

[@bigheat86]

realy nice video and beautiful handwriting

[@ANANT9699]

First of all thank you so much sir for sharing knowledge with us. My doubt is why in the O/P characteristics of CE every curve ends at origin and why not in CB(it ends in 2nd quad in case of CB). THANK YOU

[@apoorvag4188]

How did we get base current as (1-alpha)of emitter current given at the ending of presentation When the base is grounded current should be zero ?

[@mounikanayikoti2393]

Tq soo much.. really understood in one attempt..thanks for the valuable information

[@keshavmishraee5650]

Nice explanation 👍

[@dhn9987]

Your videos really very clear,. Thanks for your this videos., These are very helpful me for Ugc Net Exam.. But ,I have one doubt...mentioned as below.. Please , Explain Why in CB configuration, VCB plot gone to -ve side of axis..,? Thank you

[@venkataramanar7096]

as Vcb is increasing it means reverse bias is increasing so the width of the depletion increases and that implies the base region narrowing and now less voltage is required to keep EB in F.B and due to this curve shifts in -x axis or left side of the graph

[@avi_thegreat]

I wish my professor was clear cut like you professor. Hats off.

[@SaurabhKumar-c6s6m]

In common-base configuration, the base is common to the input and output circuits. The collector current is approximately equal to the emitter current, with a small base current. Key moments: 00:05 Transistors have three configurations: common base, common emitter, and common collector. Common emitter configuration is widely used due to its advantages in amplifying weak signals in active mode. -Explanation of common base configuration. Base is common to input and output circuits, facilitating signal amplification in active mode. -Operation in active mode. Transistor has two junctions: Junction j1 forward biased (diode EB) and Junction j2 reverse biased (diode BC) for signal amplification. -Comparison with diodes. Transistors are two-port devices with input (ie, V B II) and output (IC, V CE B) characteristics, unlike single-port diodes. 05:10 Understanding the proper nomenclature in transistor circuits is crucial for accurate representation. Kirchoff's current law helps derive key equations for active mode operation and current gain, essential for analyzing transistor behavior. -Importance of following proper nomenclature in transistor circuits for accurate representation of voltage and current. -Deriving key equations using Kirchoff's current law for active mode operation and understanding current gain in transistor circuits. -Explaining the significance of alpha as the common base current gain and its implications on emitter and collector currents.

[@settylegend1608]

[@kumaramarthaluru8349]

Really great work bro...helped a lot conceptually

[@061_arsh]

I cbo means the reverse saturation current in common base configuration when the emitter terminal is open ( battery across emitter is disconnected). I ceo means the reverse saturation current in common emitter configuration when the base terminal is open ( battery across base is disconnected). Both I cbo and I ceo are very small so they can be interchanged. Because later we have to ignore thier value anyway.

[@RitayanMitraggmu]

Sir will u make lectures on "logic families" in this series? because this portion is very confusing

[@animeshroy6437]

Sir in active mode at J2, due to reverse biasing holes will move to p and electrons to n,as they are minority charge carriers,so the direction of current should be from n to p and hence this should be the equation Ic=a×Ie-Icbo. Clear my doubt sir please..

[@tanvi_1840]

Sir I think there's one correction - proper nomenclature shld be V EB according to ur battery connection.. Pls check once

[@andromedablack5000]

Great videos. You are a life saver.

[@bubunmazumder]

For,EB diode,one can neglect RE,since EB diode is in forward bias & any diode in forward-bias-condition has very low resistance.So,from that point of view,we can say,VBE=VEE. But,how can we say VCB=VCC because in that case,RC can't be neglected since the resistance in reverse-bias condition is very high.

Thank you for lecturing. I just want to know why npn or pnp symbol uses direction in > or out < sign ? What does the direction mean? Is it voltage direction? Or current ? Please , tell us.

[@prachiargulewar2409]

This is done to indicate whether transistor is PNP or npn ..if it is PNP then arrow is from emitter towards base (this is based on direction of current ) and for npn arrow is from base towards emitter also based on direction of current.
