Problem 3: Summing Amplifier PSpice Analysis
1. Draw the circuit for a three input summing amplifier.
2. Build your summing amplifier in a PSpice file named: PreLab3_<Group#>C.
3. Use three separate VSIN voltage sources with VAMPL set at 5.0 V, 2.5 V, and 1.0 V as
inputs and with AC set at a value equal to VAMPL /V2 (six significant figures).
4. Use 100 kn resistors as the input and feedback resistors.
5. Use a 10 k resistor as the output load resistor.
6. Place voltage markers on each voltage source and on the output.
7. Run an AC Sweep from 100 Hz to 100 MHz.
8. Print a copy of this schematic and graph.
9. Use the cursors to determine the cutoff frequency of the op-amp:
fcutoff =
10. Next run a Transient Analysis on your circuit.
