Title: Noise Contribution Post by butcher_tekkotsu on Jun 29th, 2006, 11:32pm Hi all, I'm working on LNA design using Spectre. But It looks some simulation problem on NF. NF result in S parameter analysis is 5-10dB worse than I expected. So I'd like to know what is the main contributer of Noise in the circuit. Does anyone knows how to simulate noise contribution in Spectre? |
