parameter sweep / operating point (Read 2470 times)

ontheverge Junior Member Offline Posts: 31	parameter sweep / operating point Sep 29^th, 2010, 10:27pm Hi, I'm trying to sweep the width of a MOSFET and check the corresponding changes of a few node voltages and seems the command SWEEP can not be used with .op My question is, is it possible to do so without any .DC .AC or transient analysis? thanks, Stephen
