Title: VCO output impedance measurement.
Post by wccheng on May 4^th, 2004, 11:11pm

Dear all,

Could I use the s-parameter machine to measure the VCO output impedance?
As we provide the Vdd to the VCO, it will generate the frequency with the output power. If I use the s-parameter to measure the output impedance, is the result corret and will it destroy the s-parameter machine?

Best Regards,

Charles CHENG

I think u can estimate the oscillate point by this method, but the final results should be read from spectre anaylzer to see whether it's oscillating
