Impedance Reflection (11-Transistors)

How do you find the impedance looking into the base (or the emitter) of a bipolar transistor? Let's work some examples using the technique of impedance reflection.

Brilliantly explained! Have never seen this specific calculation before and it’s very intuitive to understand with this lesson 🙏

[@theoryandapplication7197]

thank you for sharing

[@ehsanbahrani8936]

Thank you professor

[@MusaYmc]

Amazing video

[@nashaut7635]

@12:00 shouldn't that be 1.2k // 1M ? Since the collector is tied at one of its ends to a DC source, it's therefore connected between the collector and an AC ground making it in parallel with the one megohm load, right?

Waiting for the next video

Thank you 😊

thanks

Can you make a series on MOSFET as well

[@synergy6294]

Mosfet or Igfet has ♾️ gate-source dc resistance ... even gate-drain.

[@user-ne4bd3ry1n]

и что с этим делать?

Why do you call R as "arse"

[@werewolf164]

😂😂😂 ... It's "R sub E", not "arse E" ...🙋🏻‍♂️🙋🏻‍♂️

[@synergy6294]

Is he real or AI generated ?

[@notaras1985]

Someone has never attended a STEM college class... .

[@adanner]

I'm real 😅 (for the time being anyway)

@@adanner the video graphics are deceptive btw but nice meeting you !
