Hey ,I am new to the field and interested in the RF field and would love to take the first step

Hi,
1) I simulated the phase noise of LC VCO at 5GHz in cadence and integrated from fl=10Hz to fh= 2.5GHz to get jitter as follows
Jc=1/(2*pi*fc)sqrt(2*integ(10^PN/10) from fl to fh)

I find it to be 960ps!!
I tried to compare with time average Jc and interated from fl=10Hz to fh=2.5GHz using cadence direct plot and I can see only 6.7f

How do I get it from phase noise skirt?

2) Also, since phase noise theoretically is boundless and becomes infinite at 0Hz, intgerating it will also give boundless value. Is it equivalent to saying that accumulation jitter is also boundless?

I tested current force, voltage measure with same sample and probe, tester, but the results (voltage level) were different when compliance level changed. Do you have similar experience or can you give me any advice regarding this?
For example,

Force [I] || Comp [V] || Measure [V]
-100 uA  || -1.5V       ||  -1.5V
-100 uA  || -3V          ||  -1.2V

Don't you need a contact layer to connect the resistor to M1?

The DRC violation is for the poly segment connecting PMOS and NMOS gates. You can add/ extend P+ and N+ implant layers between the MOS devices, such that they are touching. This will cover all poly layers by either P+ or N+ implant.

Can you clarify what is the GCD layer, please? Generally dummy fill rule deck will generate all necessary fill layers for a given design.

The "source could not be read" error means the source netlist is not available for the LVS run. Please check the netlist file path.

:D Calculation the output resistance of each stage using definition. Especially for the ac source connected @ the output.

Hey, I have a question about the sweep points limit in Cadence ADE Assembler. I've noticed that, unlike ADE XL, ADE Assembler seems to have a cap of around 1e6 points. Back in the ADE XL days, I could optimize without this kind of restriction. Does anyone know why the limit's been introduced with the update to ADE Assembler and Explorer? More importantly, is there a way to push this limit higher for extensive sweeps

HI, EVERYONE. I want to use the whole ports of a coupler including coupled and isolated ports, as shown in figure. And All the ports of a coupler can be input port and output port. However, the coupler block from AWR has predefined input ports and output ports, for instance, coupled port is defined as a output port not a input port. When the coupled port is used as a input port, there will be a error. So i wanna find another way to achieve below network.
