12.2 MOSFET Characterization

The following deck computes the output characteristics of a MOSFET device over the range 0-10V for VDS and 0-5V for VGS.

     MOS OUTPUT CHARACTERISTICS
     .OPTIONS NODE NOPAGE
     VDS  3  0
     VGS  2  0
     M1   1  2  0  0 MOD1 L=4U W=6U AD=10P AS=10P
     * VIDS MEASURES ID, WE COULD HAVE USED VDS, BUT ID WOULD BE NEGATIVE
     VIDS 3  1
     .MODEL MOD1 NMOS VTO=-2 NSUB=1.0E15 UO=550
     .DC VDS 0 10 .5 VGS 0 5 1
