Op-Amp Circuits Lab Task: Inverting, Non-Inverting and Multistage 741 Amplifiers

Programme	Electrical and Electronics Engineering with Honours
Experiment	741 operational amplifier circuits
Source signal	1 Vpk, 10 kHz sine; ±12 V supplies
Tasks	Calculation and simulation

This EEE experiment sheet gives three op-amp amplifier designs and asks for the output voltage of each, worked out with circuit theory and then checked in simulation with schematics, measurements and waveforms.

Experiment Execution and Procedure

Figure 1 introduces the op-amp pin configuration and circuit symbol. Refer to the circuits below:

Circuit 1 – Inverting op amp (Figure 2): R1 at the inverting input, R2 = 10 kΩ feedback, oscilloscope XSC1 on input and output.
Circuit 2 – Non-inverting op amp (Figure 3): input on the non-inverting terminal, 10 kΩ resistors in the feedback network.
Circuit 3 – Multistage op amp (Figure 4): cascaded 741 stages with resistors from 2 kΩ to 15 kΩ as specified in the diagram.

Tasks

Calculation: use a related circuit theorem to calculate the output voltage; show the calculation in the result section and sketch the input and output waveforms.
Simulation: simulate each circuit with related software; include the schematic design, a screenshot of the output voltage measurement and the input and output waveforms in the result section.

For this lab, write the ideal op-amp assumptions first, then derive each gain: −R2/R1 for the inverting stage, 1 + Rf/R1 for the non-inverting stage, and the product of stage gains for the multistage design. Check whether any output would exceed the ±12 V supply and clip, and show phase clearly in your sketches before comparing with the simulated scope traces. Our engineering assignment help in Malaysia and lab report writing help can guide your results section. See also the ECE5882 CE amplifier design question.
