Hello, thank you for your help.
By traponly method, you mean using the traponly option in the accuracy tab in the options of the PSS simulation?
--------------------------------------------------
As you built one yourself, may I ask some questions? you are free not to answer the questions as it's not really design.
As nothing is working I'm questionning my theory, or at least the steps I made to get to the quartz model I'm using.
To make my crystal model, I checked some crystals from manufacturers and took some caracteristics like :
Equivalent Serie Resistance = 60 ohm
Cshunt = 3pf (manufacturer saying that 7pF is max, should I take a lower value or the max value? for a worst case scenario)
Cload=10pF
With this I did some math to estimate L1 and C1 as no manufacturer are willing to give me their models.
I took a quality factor Q=10^5. From this I found L1 = 23mH and C1=0.663fF.
Does this way of creating a model good to you?
----------------------------------------------------------
Other question, I'm supposed to oscillate at 40MHz, what should the AC analysis of the open loop gain look like?
Should I have a sharp spike at 40MHz with some gain? (at least more than 1), because right now I have a slow curve, instead of a sharp spike and I'm wondering why, my Q factor is high shouldn't it be a spike?
-----------------------------------------------------------
Did you manage to make your circuit oscillate using the load capacitor in theory? Because my load capacitance should be 10pF, and I only oscillate at the right frequency with something like 0.9pF. I'm running out of ideas...
-----------------------------------------------------------
I have so many questions...
Thank you for your time,
