Using SPICE, determine and plot I C vs. V CE with I B as a parameter for a bipolar transistor with: IS = 1 nA, BF = 70, NF = 1, BR = 1, NR = 1, and VAF = 25. Use a nested sweep to obtain a single plot...

Using SPICE, determine and plot I_C
vs. V_CE
with I_B
as a parameter for a bipolar transistor with: IS = 1 nA, BF = 70, NF = 1, BR = 1, NR = 1, and VAF = 25. Use a nested sweep to obtain a single plot and consider the cases I_B
= 0, 25, 50, 75, and 100 μA.
