Lecture 09: Stability Considerations in Amplifier Design
มุมมอง 15K4 ปีที่แล้ว
Amplifiers will oscillate easily due to feed back in the Transistor. In order to guarantee stability we have to analyse the stability for all frequencies and, if not stable, insert a stabilisation network.

There's an error at 44:01. The reflection coefficient at the load is 0.34 at 140 degrees and at the input is 0.34 at -75 degrees.
At 17:44 your off diagonal terms should be minus 0.0564. You calculated the outgoing current from port 2 instead of the incoming current.
good sir, when you say gamma_L, you mean the reflecion coeff of the load if it was put against a 50 Ohm source (VNA letsy say), right? And when you refer to the S matrix of the MOSFEt, you mean the S matrix in a 50 Ohm system (so in a VNA measurement setup lets say), right?
🎉
pls stop drink/ eating during the explanation , really annoying sound came through, try to show some respect to your audience .. BR
heh? when?
Ausgezeichnet!
Ich genieße Ihre Behandlung des Themas. Gut gemacht!

Thank you for the lectures.

Its today i completely understand this...thank you so much, But indicate that "black colur" on the diagram k Is the photoresist!..
this channel helped me so much 2 years ago for my HF engineering module learning and applying smith charts to solve impedance matching network problems, thank you so much!
You should really fix the video's audio problem and reupload. This feels like it should be higher quailty video, but the audio problem deterrs me from thumbs up
Great explanation with clarity Sir. Thanks a lot for sharing😊
Danke Sören 👍🏼
Thank you for clear and detail tutorial
Why am I hearing two voices 😢
What if it's not rational angles of pi and the period only exists in certain circumstances?
The step by step theory & math calculations directly identify the value of the required physical electronic components. This presentation of the circuit diagram & Smithchart effects genuinely helped my better understand the physics theory AND practical use of a Smithchart. Thank you !
You're using the other root. t^2-2*tan(θ)-1 r:=tan(θ)±sec(θ)
Looks a lot like quantum physics to me.
it's nicely geometric in a related way. there's a clifford algebra description of transmission lines where transformations on the smith chart have some riemann sphere/mobius transformation description. or something like that; it's just worth looking up
@@pendalink The Mobius Transformation looks a lot like tangent addition. Then again, the standardization of tangent addition might be wrong, The nature of 'i' in hyperbolic and regular trig might have confused some people a long time ago. Maybe the odd functions (sin and tan) should include the 'i'. But it's fine the way it is. If we want to do hyperbolic geometry, we can just include a negative 'i' in the inverse arc functions. Most people are unaware of the issue, and this might cause them some confusion down the road.
Thank you professor I was hoping if you can provide us with the pdf for the course, it would be really kind of you, and helpful to us. Thanks in advance
Schönes Video! Wie geht es weiter ?
Thank you so much for this wonderful video..
LASER!! HELLO!! we have LASER's that work!! And we can handle the atmosphere!
Thanks for the good example and definition, Is it possible to have the Python source code?
I'm not clear on why you assume that your gamma only represents beta, and not alpha. Any context on why you just assume that?
Assumes a lossless line
Very well explained!

Muss ich für Usb kabel was spezielles kaufen? Oder geht auch einfache Ladekabeln?
Es muss natürlich ein Datenkabel und nicht ein reines Ladekabel sein.

Dear u done wrong at 5:07 The real is at 0.23 and you are right about imaginary. Thanks for such a informative lecture 😊
by completing this course would i been able to appear in job interview of Microwave Engineer?
Very good explanation.Must watch several times and commit to memory.Thanks.
Danke scho``n fu``r seine Videolektion, es hat mir sehr geholfen! von seine russisch Studenten💙
Thank you so much it helped a lot DANKE
To move the source stability circle outside of the smith chart can we add the series resister on the source side? I'm confused as to why the series resister goes on the load side.

I believe there is a mistake at 3:50 a 12.5mm long line behaves like a j50Ω inductor at 3GHz at the input. Not 2GHz.
thank you prof. From Polimi with all my respect :)
the best microwave Engineering youtuber I have ever seen
Thank you!
Very good and informative. Thank You.
Thanks!!! could u share the tools with me?
Ich mochte Ihre Erklärung, vielen Dank, Professor. Ich habe das übersetzt, weil ich nicht gut Deutsch spreche.
