Hi,

Are you talking about VCO pushing sensitivity (variation of its output freq. vs supply voltage)?

Yes, I am talking about supply pushing in VCOs. How do you do the cancellation?

Hello,

You should find some IEEE papers describing some pushing cancellation techniques.

You may find the technique in
A Multi-Rate 9.953–12.5-GHz 0.2-micro meter SiGe BiCMOS LC Oscillator Using a Resistor-Tuned Varactor and a Supply Pushing Cancellation Circuit by A. Maxim.

The paper is on edaboard, just search for it
