Hi, thanks for your reply. I will check VCO.
Could you please look at the schematic i attached. I have designed it based on a paper where the author explained the ic model, compnent value every thing and claimed the oscilation can be controlled through C2 only (from 10p to 1n) and oscilation condition depend on C1/C4= R2/R4. But somehow i cant make it work.
Please have a look if i am missing something.
Thanks
