ELECTRICAL ENGINEERING DEPARTMENT LABORATORY REPORT GUIDELINES ENEE 3720L – ANALOG ELECTRONICS LABORATORY I. General Guidelines The laboratory reports are to be submitted for each experiment by each student. The reports are to be concise and written for a reader familiar with the lab instructions. The reports should contain the following items clearly titled as to Lab Procedure Section and in the same order: 1. Cover Page: Include the title of the experiment, students’ names, and date prepared as well as lab partner’s name if applicable. See sample below: ENEE 3720L, SPRING 2019 EXPERIMENT NO.: Title of Experiment Date of Experiment: Date of Report Due: Total Pages: Your Name (i.e the report’s preparer) Lab Partner(s) (if applicable): Instructor’s Name 2. Abstract: Avery brief summary stating the experiment goals, what was done and the results thereof. It should stand alone. There should be no reference to figure numbers or symbolism that is not self explanatory. It should be the first section following the title page. 3. Results and Conclusions: This is the main section in the report. Present the plots and tables suggested in the Lab Sheets. All axes on plots should be clearly titled (including units), Plots should have Fig. Numbers with captions describing the plot without the reader having to refer to text explanations. Tables are often requested comparing measured laboratory results to analytically computed results. Along with these plots and tables, discuss the results obtained with an explanation of discrepancies between measured and computed results. A sample calculation, including the values used should be included with some brief explanation of the calculation. Generally, tables of raw data taken in the lab should be included in Appendices not in this Results and Conclusions Section. 4. References: If any references are used and cited, these should be listed in proper complete citation format in this separate section. 5. Appendices: Separate numbered Appendices can be included, containing wiring diagrams documenting your experimental setups if they substantially differ from the Lab Sheets. Refer to items in appendices using the Appendix identifying number. Additional Appendices can be included with clearly labeled raw data, and any other material you might wish to include. Page 1|2 ELECTRICAL ENGINEERING DEPARTMENT LABORATORY REPORT GUIDELINES ENEE 3720L – ANALOG ELECTRONICS LABORATORY II. Recommended Practices 1. Before the Laboratory: Prepare your Preliminary Laboratory Report (Pre-Lab). Generally, familiarize yourself with the laboratory handouts and relevant sections in the textbook. Be familiar with the circuits to be set up and the variable to be measured. In general, sort out what is to be done in the experiment before coming to the scheduled lab session. The lab sessions will be much more interesting to you with a bit of preparation. 2. During the Laboratory: Always be aware of where the power switch is located so that should an unexpected emergency occur, the equipment can be quickly de-energized. Keep in mind the ratings of all equipment so that overloads are avoided. During the laboratory session, I would suggest transferring your raw data into Excel, and plots what is suggested in the lab instructions. This should be done to see that you have valid data, and also to have the lab TA help with your understanding of the experiments. If this procedure is followed then much of the work needed for the reports will be done during the lab session. 3. After the Laboratory: Work on the report while the lab is still fresh in your mind. The report is to be graded both for proper technical English style, and for its technical content. A major goal of this lab is to provide experience in technical report writing as well as demonstrating and clarifying the theoretical material presented in the lectures. When preparing plots of multiple variables taken as one other variable is being changed, it is generally a good procedure to put all these plots on a single set of axes. If these plots are made using Excel, then different y-axis scales may be needed, or the variables can be normalized to be some fraction of a base value (i.e. use the per-unit system). Clearly label each curve, and include base values if a normalization of variables is used. Neat hand-drawn plots are acceptable, as well as clear hand-written sample calculations. Page 2|2 ELECTRICAL ENGINEERING DEPARTMENT ENEE 3720L – Analog Electronics Laboratory Laboratory #1 – Inverting Op-Amp Objective: The purpose of this experiment is to perform analysis of an operational amplifier circuit, Inverting and confirming selected resistors satisfy design specifications for voltage gain, closed-loop gain, G. Analysis will consist of implementing the circuits in the laboratory and taking measurements. Equipment: • LM-741 • Assorted Resistors • Functional Generator Procedure: Figure 1: Inverting Operational Amplifier 1) Design the circuit in Figure 1 to achieve a gain of -10. Specify the values of R1 and R2 used to achieve the gain. Measure and record the R1 and R2 values. What is this type of gain called and why? 2) Using the functional generator, apply input sine signal of 1-kHz with 50mVpk−pk, VIN. Use dual dc supply connection to have ±15V to bias your Op-Amp. Why do you need to bias the Op-Amp? 3) Using an oscilloscope, observe and record the output voltage, VOUT waveform. 4) Gradually increase the frequency of the input sine wave until the output’s amplitude is about 70% of step 2. Record the frequency at which this happens. 5) Gradually increase the amplitude of the input sine wave until the output becomes distorted. Record the amplitude at the point you start to see the distortion. 6) Repeat Steps 2 to 5 for gains of -2.2 and -1. 7) Using a power supply, provide a DC input to the circuit, VIN in increments of 0.1 V, from -1 V to +1 V. Record the values of VOUT and plot your results. Lab #1 – Inverting Op-Amp Page 1 of 2 ELECTRICAL ENGINEERING DEPARTMENT ENEE 3720L – Analog Electronics Laboratory Laboratory #1 – Inverting Op-Amp Report Discussion: 1) How well did your simulation results match your experimental results? Please explain any discrepancies between the hand calculations, simulations, and experiments. 2) Recalculate the theoretical gains of the circuit using the measured resistor values. Are the recalculated values closer to your measured gains? Determine the percent error. 3) What does the frequency in Step 4 represent? 4) Why did distortion occur in Step 5? Explain the reason.

Objective:
The objective of the experiment is to perform analysis of an operational amplifier circuit,
inverting and confirming selected resistors satisfy design specifications for voltage gain,
close-loop gain, G. Analysis will involve implementing the circuits in the laboratory and
taking measurements.
Abstract
Operational amplifier is a high gain voltage amplifier that is usually assembled in form of an
integrated circuit. As the term “operational” suggest, it date back in the days of analog
computers when these devices were used to perform mathematical such as integration,
addition, subtractions and the solutions involving differential equation. In today’s life,
operational amplifier is used in variety of circuits devices which functions in lower power
and voltage.
Operational amplifier consists of linear circuit which form the core of its operation. The
circuit is a quite complicated device consisting of passive and active devices integrated into
silicon. This complexity requires experienced experts and engineers and enough to design.
However, in the first order, the input-output are simple design. The designer using
operational amplifier need not to be so much bothered with the inner workings of the circuit
but treat it as a “black box” containing specified and desirable properties. For that reason, the
