EHB211E Basics of Electrical Circuits
HOMEWORK 3
For the PSpice solutions, provide the schematic showing the voltage and current values and
the output file.
1) Calculate v0 in the op amp circuit of Figure 1 for given Rf values assuming all op amps
are ideal. Also, obtain and show v0 using PSpice program.
a) Rf=10kΩ b) Rf=∞ (Open Circuit)
Figure 1
2) Design a single op amp circuit with C =2µF to generate the given function below by
identifying other component values.
3) For the op amp circuit in Figure 2, obtain the differential equations for v0(t).
