Objectives: To study and analyze the Operational Amplifiers (Op Amp) for implementation of Inverting Amplifier, Non-Inverting Amplifier, and Summing Amplifier. Prelab Activity: Watch YouTube videos on Op Amp: https://www.youtube.com/watch?v=idJEMYhrIfs List of Equipment: Solderless Breadboard Power Supply: Keysight EDU36311A , Triple Output, Programmable DC Power Supply Multimeter: Keysight EDU34450A 5½ Digit Digital Multimeter Keysight EDU1052G , InfiniiVision oscilloscope Keysight EDU332105 Arbitrary-Waveform List of Material: Multisim software running on PC LM741 Op Amp (Quantity 1) Lab Number 9 Tech 63, Analog and Digital Circuits Op Amp Amplifier Implementation Keysight EDU36311A , Programmable DC Power Supply Keysight EDU34450A Digital Multimeter Solderless Breadboard Keysight EDU33210 Arbitrary-Waveform- Generator Keysight EDU1052G oscilloscope

10 kΩ resistors (Quantity 1) 100 kΩ resistors (Quantity 1) Procedure In this experiment, you will experimentally build various Op Amp circuits such as inverting amplifier, non-inverting amplifier. Part I) Inverting Amplifier Examine the inverting amplifier shown below and build the circuit with R f = 100 kΩ and R in = 10 kΩ with V in =1 kHz sine-wave with peak amplitude of 0.5 V. The output voltage is given by the equation V out = - (R f / R in )V in . Part II) Non-Inverting Amplifier Examine the non-inverting amplifier shown below and build the circuit with R f = 100 kΩ and R in = 10 kΩ with V in =1 kHz sine-wave with peak amplitude of 0.5 V. The output voltage is given by the equation V out = [1 + (R f / R in )]V in .

To-Do during lab session: ( explore, explain, and analyze ) For this lab assignment use a three-prong approach by conducting: a. Hand Calculations: Explain and discuss the concepts and components – instructor to student, student-to-student in groups. Review the operation of the each amplifier in parts I and II. Determine the output voltage (using rms value) and the gain in relation to external resistors. b. Multisim Simulation: Conduct Multisim simulation and verify operation of the circuit and values obtained previously. Include screenshot of the Multisim simulation for each parts I and II in your lab report. c. Circuit construction on the Protoboard: Construct the circuit on the protoboard and verify operation of the circuit and values obtained previously. Include screenshot of the circuit for each parts I and II in your lab report . Review the pinout for each amplifier for proper connection of the inputs and output. Verify operation. Provide picture of your operational circuit and include in the lab report. Mount the Op Amp on the breadboard. Connect Vcc to +15 V and - V EE to -15 V. Set the function generator to a 1 kHz sine-wave with peak amplitude of 0.5 V. To verify the operation of the circuit, connect the circuit as shown, Adjust the oscilloscope setting, monitor the output with channel “B” of the oscilloscope and he function generator with the channel “A” of the oscilloscope. Change the color of each trace to clearly identify the input and output. Analyze and compare the values from hand calculations, simulation, and the breadboard circuit. Transfer the data into the table shown and calculate the percent error. Data Table for Part I (include rms values for voltage values):
