Title: Plotting OIP3 vs IIP3 using Hspice+AvanWaves Post by Syahrizal on Jul 24th, 2005, 10:37pm Dear all, Does anyone here uses HSPICE? I have spent a lot of time looking into plotting OIP3 vs IIP3 to find 1db-compression point and third order intercept point using the normal HSPICE. There are no manual available for such plot, but I believe there must be a way to do it. Just wondering if anyone has come across it and successfully solve it. Thanks a lot |
Title: Re: Plotting OIP3 vs IIP3 using Hspice+AvanWaves Post by spiceoracle on Aug 10th, 2005, 12:48pm Plotting OIP3 and IIP3 using HSPICE is not possible. HSPICE will not show non-linear effects such as compression points or intercept points. If you want to simulate non-linear effects, you will need to use HSPICE RF. You can then measure OIP3 and IIP3 using CosmosScope. |
