ECE 403 Homework 3
Due in class before lecture on Friday, 1/30/9
Use the nmos test schematic with sources Vds, Vgs, and
Vsb like from the last homework (as shown here), for
both problems in this HW.
Use the properties editor to
display the “name and value” of L and W on the
schematic, as shown, and set their values as shown.
Use the model editor to make M1 have the model
parameters VTO=0.7, GAMMA=0.5, PHI=0.7, which
I’ve taken from Table 1.2 on page 64 in Johns and
Martin.
In addition, include the model parameter
KP=100u and LAMBDA=0.05, which will simplify
your calculations by overwriting the corresponding
values that SPICE calculates from the other model
parameters. Along with your calculations for each
problem, please
hand in
the corresponding SPICE text
output file (the “.out” file) and
indicate on it
where
your property values for L and W are,
and
where your
model parameters, VTO, KP, GAMMA, PHI, and
LAMBDA are.
In addition
, hand in your PROBE
traces for each problem.
