yig filter linearization
Hi, guys
I am designing a LC VCO using MOS varactor. And I need ur help.
The OSC freq vs. vtune is a nonlinear curve. I am required to linearize it.
I have tried to use resistors to bias a group of Varactors at different voltage level. But the Phase Noise suffers from the resistors, and additional current consumed by the resistor.
So is there any way to linearize the Vtune vs. OSC freq without degrading the VCO phase noise?
Thanks a lot!
