Work requirement :
please read the exercise of page 117 from the spice book, but simulate the device model parameters and
operational point at 30 degree and 100 degree.
Please Run the TEMP analysis with Pspice and answer the question of the exercise Please hand out a e-report about your work I.
Net-lists and circuit figure :
And the net-list file goes :
EX3 DC Analysys exapal1.2
.MODEL MELQ NPN BF=100 IS=1E-16 Q1 2 1 0 MELQ RB 3 1 200K RC 3 2 1K VCC 3 0 DC 5 .temp 30 100 .OP .END
II. Simulation result :
According to the output file, we can draw a table to contrast the difference:
a.
b.
III. Conclusion:
With an inspection of the circuit parameters in different temperatures, we can find that the value of IS changes largely, about 1000 times, and GM, about 16 percent, while about 500mv decreasing on VCE caused. So the behavior of Transistors can be affected by temperatures largely.
