Lab 2 - Summing Amplifier

Objective

1. Verify the simulated gain from the summing amplifier through experiment.
2. Verify the simulated waveform from experiment.

The Summing Amplifier Circuit

Equipment

Simulation

• Cadence OrCAD for simulation

Real-World Measurement

• Breadboard
• Circuit Components from the schematics
• Oscilloscope
• Power Supply
• Signal Generator

OrCAD Simulation

The three waveforms on the top correspond to V1, V2, and V3. The bottom one is the Vo

A closer look at Maximum and Minimum Value of Vo

	Vo (V)
Max	-0.213
Min	-3.35

Real-World Measurement

Vo

	Vo (V)
Max	-0.200
Min	-3.46

Summary

The OrCAD simulation is fairly consistent with the real world result.

	Simulated Value	Measured Value	% Difference
Vo Max	-0.213	-0.2	3.2
Vo Min	-3.35	-3.46	6
