I want to use CPPsim, which is a free software developed by Michael Perrot Group in MIT.
http://www-mtl.mit.edu/researchgroups/perrottgroup/cppsim3.html
However, I have could not downloaded it for several days. What's wrong with that official website? Or can you share with me if you have a copy?

Hi Carlos, Its Halesh here, i am looking for the Design of VCO Ring Oscillator, i started studying some architectures, but finding difficult to understand. so can you mention me some reference which expains complete VCO design

Hello, Halesh-Do you have access to IEEE papers? Also, many sources are on the web, e.g. http://en.wikipedia.org/wiki/Ring_oscillatorA general approach for ring oscillators is to simply cascade CMOS inverter stages or differential inverting amplifier stages. The frequency is tuned by adjusting either device size, capacitive loading on each stage, or by adjusting bias current (or current starving) each inverter stage. Note that you should use a prime number of stages to avoid harmonic patterns of oscillation.What in particular would you like to better understand?
