Measuring phase noise in spectre
Mar 22nd, 2006, 12:28pm  
Hello,

I am simulating a Quadrature VCO in Spectre. Can anyone tell me how to measure phase difference between signal using calculator in Spectre? Right now I am exporting data in MATLAB and doing it, but its a long process.

Thanks.

If you have SpectreRF, perhaps you could do an autonomous PSS analysis and then extract the phase difference from the Fourier coefficients of the fundamentals at the nodes of interest.

I want to measure phase difference between I and Q signals. But by mistake I wrote phase noise in subject. Sorry about the confusion.

Thanks.
