Simulate an oscillator with ADS

[ANA BASHIRI]

Hi dear friends
Sorry I do not speak good English.
I have a problem
If possible, please help me
I need to simulate an oscillator with software ADS
An example is solved by the simulation results
I have to simulate it I get exactly the same results
But I do not know AND
My time is low.
Examples here would be
If possible, please help me

First construct the essential part of the circuit. Experiment until you get it operating.

This simulation shows the LLC tank, the cross-coupled mosfets, and their arrangement as a long-tailed pair. It is done in a different simulator but you can see it works in a similar fashion.



Oscillations go back and forth around the LLC loop. Some asymmetry is necessary in order to get oscillations going. If oscillations do not start, then try increasing current through the bottom transistor (or mosfet).

The values produce 7.3 GHz (which is the frequency referred to in your text).

This may be enough to help you get through the rest of the lesson.

Thank you
I have no problem working circuit
I want to simulate the circuit in ads
And compare the results with my answer?
For example, instead of varactor I do not know what element in my ads?:?::?:
