I know little about jfet's. So, I started playing with a model I took from onsemi. The only parameter I can match to the datasheet is VTO.
I tried dc v2 -1 1 .1 and looked at v1#branch and v2#branch. Not what I expected. So, I think I am doing something wrong. tomdean .MODEL 2n5486 njf ( VTO=-3.91171 BETA=0.00078986 LAMBDA=0.0104371 RD=3.58556 RS=3.44889 IS=1.44179E-14 CGS=430.467E-15 CGD=433.667E-15 PB=1.160107 FC=0.5 KF=6E-18 AF=1 VTOTC=0.002 XTI=3 BETATCE=-0.5) *^^^^^^^^ End of included SPICE model from ../../Models/2n5486.model ^^^^^^^^ * *============== Begin SPICE netlist of main design ============ V1 4 0 5 V2 2 0 .1 * +-------- D * | +------ G * | | +---- S * | | | J1 3 2 0 2n5486 R1 3 4 2000 .end _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
