01:28 The common base configuration of a transistor involves the base being common between input and output. 02:56 Transistor base configuration involves forward and reverse bias junctions. 04:24 Common base configuration allows for input signal amplification. 05:52 Alpha dc is the current amplification factor. 07:20 Output characteristics of common base configuration 08:48 Understanding output characteristics of a Transistor 10:16 Ic is approximately equal to Ie due to reverse leakage current. 11:44 Transistor has three operating regions Crafted by Merlin AI.
Thanks sir for the explanation. Please why is the horizontal axis of the Dc load line of a common base amplifier marked as VCB and not VCE? I got a couple more questions but i will need to send you photos so you can understand me better. I look forward to an early reply sir. 🙂
No worries.... But there is nothing in this to get confusion You just make sure the FB and RB sections There you can find loadlines And you can get about VCe Vcb.....
Ini bicara hubungan arus colector (Ic) dg Vbc, dimana pd Vbc tertentu arus colector (Ic) tdk bisa naik tajam atw melandai, dan Vbe diturunkan pd Vbc akan naik maka pd Ie akan naik seperti yg ada pd grafik Ie dg Vbe.... Dan arus colecktor (Ic) dg arus emiter (Ie) sbg bandingan dr Ic/Ie= Alfa, jadi Ic < Ie atw Alfa < 1.... Input Vbe terlihat hubungan arus emiter (Ie) dg Vbe dan Vbc dlm common base...
It is the condition for biasing of BJT. Vbe should be forward bias and Vcb should be reverse biase. So it depends on the type of transistor, which polarity should be connected to the terminals of the transistor... Do subscribe and keep supporting EC Academy 👍🏼
It is the revers leakage current from collector to base… it is very very small current … Hope this is helpful… Do subscribe and keep supporting EC Academy ✌️
For npn.... reverse the polarities of the voltages and reverse the direction of current.... the explanation and graphs remains same. SUBSCRIBE and keep supporting EC Academy 👍
Watch the following 👇video... you will easily understand what is alpha #21 Transistor (BJT) current components || EC Academy ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zUZnBSiHth0.html Subscribe and keep supporting EC academy 👍
It will depend on current flow… if current is flowing from base to emitter then we will consider Vbe. if current is flowing from emitter to base then we will consider Veb. Hope this is helpful… Do subscribe and keep supporting EC Academy ✌️
