[1]
Pierret 5.1 (all parts)
[2]
Pierret 5.4 (all parts)
f) calculate the zero bias depletion capacitance of this diode (in fF/µm2). Note
that area is not needed for specific capacitance.
[3]
Pierret 5.11 (part a only)
[4]
Pierret A.2 (p. 508) (all parts except part g)
[5]
Pierret C.2 (p. 513) (all parts except part e)
[6]
a) Prove that the slope of an ideal diode current rises at a rate of 60mV/decade
at 300K.
b) What rate would you expect for 77K?
[7]
Pierret, 6.13 (all parts)
[8]
a) Find I and V in each of the following circuits using the ideal diode model.
b) Repeat using the constant voltage drop model (take Von = 0.7V).
[9]
Find the Q-points of both diodes in the following circuit using a constant voltage
drop model (take Von = 0.75 V).
[10]
Use SPICE to Jaeger 3.102 (must show evidence of your work – i.e., an output
plot, a .cir file, etc.) Note: No ripple calculation needed.
