Hello

What is supply pushing cancellation?
What is supply pushing?
 

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.
regards.
 

Hi can any of you tell me where is this technique used?
 

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
