Hi, I have already tried out different topologies in RO design...Not achieving results, That's why i brought this up to the forum. I have already tried out current-starved CCO, Differential CCO, CML topologies...All of them offer Low phase Noise at Lower Frquencies, but none of them are meeting my noise specs at around 1GHz....What i want to be sure is -- Are these topologies capable of giving such noise performance at given power levels & i am not designing them correctly , Or I can rule out ROs and go for LC?
Just wanna be sure to rule out Ring Osci....
regards, Mayank.
