I'm working on a design problem that says to check the spec sheet of a 2N5951 N-Channel JFET for its gm. All I see on the spec sheet is gis, gos, and goss. Is it one of these or is it not stated in the spec sheet I'm looking at? Here's the link for the spec sheet.

 

I post the datasheet: http://www.fairchildsemi.com/ds/2N%2F2N5951.pdf

have a look at this: http://www.kennethkuhn.com/students/ee351/jfet_basics.pdf bottom page 4
