let's assume I have completed the entire design and layout, with all simulations (EM and RC extraction).
And I get the same different IIP3 value on the right and left.
Will the same behavior happen again in the measurements?
When the difference is 1-2 dBm it's ok, but here for example now in...
Hey, everybody!
I am simulating an LNA with high linearity using Derivative Superposition Method. (This is just the core LNA without matching on NFmin and output. GAMax values are now 15 and NFMin 1.5 which I am quite satisfied with for now).
(I guess the specific method of increasing...
Hi everyone,
I was wondering if it is possible to get NF from Single-ended to differential LNA measurements using Friis formula?
The complete measurement setup looks like this
I need to determine the NF for the LNA.
I have checked this solution using matlab.
(lets Assume that the NF...
I see your point.
About the lumped simulation - nowadays I came across a set of carpet pad files for EM simulation, which includes files for nominal, and corner cases (That is, several carpet pad files are presented in the PDK).
I just see from my colleagues at the university that the lumped...
In other words, let me ask the question again.
Let's imagine you design devices which operate at 8- 20 GHz on CMOS SOI or SiGe BiCMOS technology.
And all models of passive components in the PDK are represented as black boxes of 2 kinds - one of them, a black box, inside which Spice model of...
Let us assume that we have a broadband lumped element model in the frequency range 0 (DC) - 30 GHz, and we have the results of an EM simulation in Momentum Microwave or HFSS in the range 0 - 30 GHz with a step of 0.1 GHz.
For simulation in DC/AC / HB modes will there be a significant difference...
Simulation of passive components
How much necessary to use the Lumped element model of passive devices (inductances, transmission lines, baluns) when designing MMIC devices on the CMOS SOI technology?
If you need to run an EM simulation in the end for a complete layout?
I mean, if instead of...
I need to apply scale functions to an existing coil layout.
In fact, I just want to apply the following AEL functions to the AEL artwork to scale the existing design
de_select_all();
de_set_scale(0.8, 0.8); // de_set_scale(scaleX, scaleY);
de_scale(0.0 0.0); // complete the scaling procedure...
Hi all.
I am modeling one phase shifter cell in Cadence Virtuoso and want to get the following plots:
Phase (S21) when Vcntrl = 0 V
Phase (S21) when Vcntrl = 1.2 V
Also the phase difference in these two states
delta Phase (S21)
I am trying to simulate this in ADE XL and I get graphs for...
This image of the stack is not from the DRM)
This is from open source https :// tel.archives-ouvertes.fr/tel-00445302/file/ChapterIII.pdf
But it's very similar to what I have)
I think this picture is as similar as possible to what I have in the DRM

PadOpen layer - serves as a sort of marker - Al layer is applied directly to M7. In other cases Al and M7 are isolated by dielectric
Not sure if PadOpen layer can be considered - as metal layer over M7 or as Via...
Right now I have the total thickness between Al and M7 (0,5 + 0,035 + 0,6 + 0,04) - In order to place the MIM capacitor there.
Because of the large thickness of the dielectric there may be additional capacitance, that shouldn't be there.
If I make the thicknesses of these dielectric layers...
Thank you so much for your advices!
About the top metal - yes, according to the DRM it uses a thick layer of Aluminum.
And to be honest, this is the moment that raises the most questions for me.
Could you please explain more about the C and the top metal?
A MIM capacitor, (MIMTOP and MIMBOT)...
