Hi, in a 1999 paper Ken Kundert mentions that simulating this really important effect was not yet possible that time using a real free-running VCO driving a mixer with interferer at the RF input. I wonder what is the situation now - 13 years later - in SpectreRF or ADS, or whatever? I checked that tran noise is correctly transfering the LO phase noise into the IF output but hbnoise still not  :( .
Has anybody information on this?

Bye Stephan
