Hi Erik ;-)
I assume you're talking about the Spice Models Documentation that goes with the PDK, not the .scs files themselves (because they do contain of course this information but it is...well...a bit encrypted :-P)
In fact, I did find this morning the sigma values I was looking for, for my...
Hi everybody,
here's my question: in a former (BiCMOS) process I've been designing with, I used to size resistors and (especially) MOS devices also based on matching parameters, namely using a
\[\sigma = \frac{\sigma_A}{Area}\]
type of expression to evaluate the needed area in order to stay...
Thanks Mazz,
I've seen they have some interesting course in Lausanne, although the "meat" was in Hong Kong in January...(Lots of Razavi, whom I'd really be interested to meet)...Maybe they'll repeat that soon.
Any other suggestion besides Mead?

Hi everybody,
I'm an EE with some years experience specifically in the Radiofrequency Microelectronics (7-8 yrs), plus some other @board level microwaves.
I am looking to "enhance" my understanding of this world and to do this I think a good course would be a proper tool.
I've thrown a couple...
Hi Dick,
I had prepared a nice reply to you but it somehow got lost in the "re-login" process :x
Anyways, as I tend to do when there is a concept I can't grasp, I reduce it to a very simple - yet partial and not correct - type of problem.
The background of my question is that I come from a...
Re: MOS Mirrors - Accuracy.....
Thank you very much JoannesPaulus,
I would never have thought such accuracy to be possible. But this is just because I took for granted some "rules" without thinking about them critically.
I think the reasoning goes like this: the technology will give you some...
Hi Joannes,
thank you for your reply. So that means - for the sake of putting numbers - that you have a ref current of 1uA and your output current is in the range of 300*(1±7.5)uA? (I'm taking your 5% as a plus/minus...Or is it ±5% what you intended?).
Now another question (which is actually...
Hi all,
simple, straight question: what is in your experience (i.e. possibly measured things) the maximum mirror ratio realizable without "tricks" like trimming (or what else?).
I mean, I can make a transistor "big at will" and I want to implement a current ratio of 1:n or n:1, what is the max...
Hi Erikl,
this is exactly what I cannot believe. It may be true, but intuitively I don't expect their accuracy to be that high. In other terms, I expect such a process to provide me a resistor having a L = Lo ± Δ(L) and this Δ(L) being a statistical value whose σ is larger than 5nm for Lo =...
Hi Erikl,
probably I didn't make my point clear enough. What you say is without the slightest doubt what I am used to bare in mind when designing.
Here I find myself, however, with an already made design using odd resistor values. Besides considerations of PVT variations, which is the main...
Hi everybody,
I'm dealing with a TSMC 0.18 design, which I am new to and there is something I am quite puzzled about, although other designers take it for granted...
So here' s the thing: I call layout pitch the minimum delta between two layout dimensions. For instance, if you can have a...
