I'm sure many of you have seen the video on fabrication. I've seen it twice and it was really fascinating and I want to add a copy to my collection. Does anyone here know where is that video located here?
hi there, so have you figured out how to do it? I just learned how to do matching. This is very interesting thing and I would like to know the solution too. If you found out the solution, please shred some light me.
Of course it affects the Q, if you included all the two main caps Cgs and Cgd at HF then write your transfer function. You will get a second order system, you will get denumerator as S^2 + w0/Q x s + wo^2. If you include that Cgd of the CS into the transfer function you will see that not only...
if it has negative real part then something is wrong and can cause oscillation due to reflection waves. Where are you div your RI? Is it at the load? It should be at the load.
T.Lee book is awfully difficult to understand unless you had experiences. But then again if you already knew your stuffs then why would you need a book anyway.
I like Razavi RF Microelectronic book better even though it was carelessly written and it seems like he rushed that book out too fast...
Klouly, I have ADS software. I want to learn how to use it, do you know what are the best place online that provide a free crash course on how to use it?
right, I understand that. How to select my passive element or even using a transmission line, i.e. how to navigate around the polar chart. But what I don't understand is
1. Does a perfect match have to be exactly on the origin point? Or can it be anywhere along imag = 0 and anywhere on real...
I don't have that book. I don't need deep understanding of that filter either. I just just need a quick overview of how does its characteristic looks like because I googled and I found none descriptive definition.
how does it looks like? Is it a bandpass filter like SAW or is it a notch or LP or HP? This one book I'm reading keep mentioning but I just couldn't imagine how it looks like.
homodyne transceiver
So is it true that 99% of the transceiver today are based on homodyne design for its simplicity? Is that true? I was told by someone but I just want to more inputs. Thanks guys.
Thanks guy. I just went over the Cheng EMC book and understood Smith Chart. What I don't get the most is how in the world can you get your starting point on the smith chart? Do you just put your 50ohm input to any transmission/ckt. Then using a simulator like Cadence to tell you where is...
To avoid miller you should always use Cascode or CG setup. Miller only happens in CS amplifier because you have that Cgd cap and it can really limit your bandwidth at high speed. w3-db = 1/RC and C=Cgd(1+K). You see C is getting amplified by its own gain, the denumerator gets really large and...
so you guys are saying that we can not start with smith chart for hand analysis. So I have to use a program for that then deciding whether to add L/C in series or parallel?
Added after 2 minutes:
btw, smith chart is only for passive devices only right? I can't use it to match impedance for R?
