LC VCO design using cadence

lc vco

Are there any tutorials, or step by step guides that can be of help designing, or rather putting togheter a LC VCO?
I would like to make a VCO with as good as possible linear characteristics, low jitter, and preferably low power consumption.
I sort of know how to apply different analyses to circuits(using cadence), but to get there, i need to know how to best put the LC VCO components togheter, and what values to apply to the components ( the L, C, and R's the semi conductors(cmos), supply voltage, etc.) The size and what configuration to use for the varactor, to get a wide tuning range.

Are there any LC VCO schematics in cadence available for viewing, testing?
I need to get an over all understaning of how the different components work togheter....

lc vco tutorial

For the vco simulation, you can refer to spectrerf in openbook of cadence
For the schematic, you can refer to the book about rf design.
Try to change the value about the VCO and find what you wish.

In cadence ic design tool, there is a sample for how to simulate differential LC VCO, it is under dfII/sampls directory. You can read the Spectre RF user guide for more help. For component selection, A-Mode varactor is a good device for variable capacitor, the inductor and active devices are dependent on what frequency your VCO is working on.

cadence vco simulation

I want to use spiral inductor to simulate LC VCO. But I can't use its layout. Cadence show that it can't calculate the maximum number of turn. I think I lose some skill files.
Can anyone help me to solve this error?
Thanks

vco design

cadence has some samples

cadence vco

Can you say more detail? Which samples show how to use layout of spiral inductor?
Thanks

vco cadence

Maybe ADS is better for your simulation.

Hello
you can start by razavi or tom lee to understand the basics , then you can read ieee papers of ali hajimiri for further understanding the vco mechanisms, then you can read state of the art ieee papers vco
