Injection lock vco

$

Hi all,

Is there any guide that helps me simulate an injection locked vco ?

All I know for now is: run a transient simulation and let my oscillator reach the steady state and then I use a switch to connect the Injection voltage using a varactor and wait for it to lock to finj.

How can I obverse the final fundamental tone using pss ? Can I observe phase noise using pnoise simulation ?

Do pss and pnoise work with switch component ?

This is what I am planning to do. Using a switch to connect the injection signal to VCO using two varactors.

Thank you. I appreciate your time and effort.
