lc resonator
Hi all,
Might be basic stuff, but I feel really tired these days.
And obviously, I am quite in a hurry !!
I hope you could help me
Here's the problem.
I have an inductor, modelized by its S-parameters, imported from Momentum to ADS as a component.
I'd like to make this inductor resonate at a certain frequency, with a parallel capacitor.
Until here, everything's ok.
But now, I'd like to modelize this frequency resonance.
So, I connect all the things as it
- "Term" component to the capacitor, and ground
- The capacitor component in parallel of the "inductor"
- The LC parallel is connected to ground.
Guess you can imagine it
Now if I start a S simulation, I find S11 resonance at my frequency, identified by the notch... well, the valley... well, a gap... I can't find my words in english today
If I want to see a clear and perfect notch, I should put a source impedance quite high. The question is: why ?
And the bonus question is: if I want to drive this LC tank with something, should I show him a high impedance level ?
Thanks a lot in advance for your precious answer.
Regards
