I simulated a transmission line in cst (ver.2017). I used no loss tangent nor lossy metals (just PEC and perfect dielectrics). I ran a simulation over 1G to 5G using the frequency domain solver. I got the following s-parameters
I checked these results with other simulators (ADS) and they are...
So I basically designed this inductor ( 2 turns, inner radius=60u, spacing=4u, width=10u) in both sonnet and momentum. The metal layer M9 has a thickness of 3.4u. the under bridge M8 has a thickness of 0.9u. I also manually designed the stack up in both softwares.
I set the maximum cell size in...
I've went through each folder and each file of the documentation of the pdk, but I didn't manage to find any document describing the layers used during the layout. Is there any way I could extract the full name/ purpose of each layer from the pdk?
Greetings all,
Could someone please help me with the following issue?
I have a cell that contains a schematic and layout view. The layout was generated from schematic window : Launch->Layout XL->Create new...
The problem is when I select a component from layout, like this
This component...
Greetings all,
When I open the layout view of a spiral inductor from a pdk I was given, the layout looks like this
I am still a newcomer in layout design, but I do know a spiral inductor is supposed to look something like this
The octogonal shape isn't even appearing in the layout above...
Hi all,
In this PhD thesis (page 10) about some dust particle detector that was based on an RF chip , we can read
" Since this thesis was the first attempt in this way, there were not any primary experiences, or guide lines or even predefined parameters and characteristics
for the RF front...
By thickness i mean the distance between the inner length between the two radii (the value of the radius chosen for begin layer and the value of the radius chosen for drill). This is how I see it in my head
Is this representation accurate?
I wanted to create the pad file for a thru-hole pin using pad editor. The hole has a 1mm radius. I set BEGIN LAYER to 2mm.
Is BEGIN LAYER the copper layer adjacent to the hole on the top side of the PCB? And if I set its radius to 2mm would this mean the copper pad ring will have a thickness of...
Greetings,
I tried to simulate the simple following power divider in schematic in ADS 2016,
I got the following s parameters,
Then I made the same circuit in layout and run a momentum microwave simulation,
As you can see, the results were very different from those obtained...
