The Noise Analysis option provides an output variable "xxN_1overf" (xxN is the device name, like qq1) for active devices (diodes, transistors). In a circuit I am simulating the 1overf variable is the dominant noise source, but I don't understand/know what this variable is referring to (I'm suspicious its related to some sort of overflow threshold) - I cannot find a reference to a 1overf variable in any convetnional Spice manual, so it seems to be unique to Multisim.
Also does anyone know if the "xxN_id" output variable is the shot noise component or the flicker noise component (or maybe the vector sum of these). Spice normally differentiates shot noise from flicker noise by calling shot noise NSID (or NSIB/NSIC) and flicker noise is called NFID (or NFIB). If, as I suspect, Multisim is just adding shot and flicker noise together, is there any way of splitting these out?
Best regards
