The abstract is a short description of the laboratory assignment and goals in one or two
lines with some specifics if necessary.

I. PROJECT DESCRIPTION
(1 POINT)
This section should tell why the experiment was performed. The purpose involves
specific principles, circuit topologies, and/or measurements. These need to be explicitly
stated. It is not sufficient to say that “The purpose of the experiment was to familiarize
the student with non-ideal behavior of operational amplifiers.” An acceptable form
would be “This experiment examined the effects of non-ideal characteristics of
operational amplifiers on simple inverting-amplifier circuits. Specific non-ideal
characteristics include limited gain-bandwidth product, limited slew rate, nonzero input
bias currents, and nonzero input-offset voltages.”
II.
THEORETICAL BACKGROUND
(4 POINTS)
This section contains the theoretical background of the experiment including relevant
mathematics.
III.
METHODS AND MATERIALS
(4 POINTS)
This section should contain a continuous narrative of how the experiment was performed.
Information contained within this section should include a listing of the equipment used
in the experiment and a description of the experimental procedure.
Equipment
Use of a table to list the hardware and software of an experiment is required. Include a
list of apparatus containing each item of test equipment, described by function (e.g.,
“Arbitrary waveform generator”), manufacturer (e.g., “Agilent Technologies”), and
model (e.g., “33120A”). Software must also be listed (e.g., “NI-Multisim”) as well as
any application programs developed for the laboratory. In the case of application code
written by the faculty or by the experimenter(s) (such as LabVIEW virtual instruments or
MATLAB scripts), the date of the code and the name(s) and affilitation(s) of the
author(s) must be given; in addition, the function of the code must be briefly explained.
Test circuits which are themselves not part of the device under test must also be listed.
Schematic diagrams of these test circuits must be included in the report narrative.
Experimental procedure
The procedure followed by the experiment is given here. The source of the experimental
procedure must be cited unless it is an original procedure devised by the experimenter(s).

“The laboratory procedure was conducted in accordance with EENG 4409 Laboratory
Experiment #1, written by D. M. Beams, Department of Electrical Engineering, College
of Engineering and Computer Science, University of Texas at Tyler, dated 3 June 1998.”
An experimental procedure distributed in class must be referenced, but the reference is
not sufficient in itself. The narrative must contain enough detail to permit a technically
trained reader to replicate the experiment without having access to the original
procedure.
Figures of circuits and of connection of experimental apparatus will be shown as
appropriate in either schematic form or block-diagram form. Include any calculations
necessary for the experimental procedure.
IV.
RESULTS
(8 POINTS)
This section of the report contains all measured, simulated, and calculated results. This
section must be introduced by narrative text. All data will, whenever feasible, be
presented in tables and figures. Include hand calculation, pictures of (oscilloscope,
multimeter, bread-board, NI-Multisim, graphs) in this section.
V.
DISCUSSION
(1 POINT)
Discuss the implications of your work. For example: “The value of input-bias current of
the LM324 operational amplifier determined by experiment was −200 nA, which is 80%
of the maximal value given by the manufacturer’s data sheet (−250 nA). This input-bias
current resulted in a drift of approximately −1.1 V s−1 in the output voltage of the
integrator circuit of Fig. 5 after the switch was opened at t = 0. Thus the LM324 is
unsuitable for use in this integrator circuit.” Compare results of theoretical calculations
or simulations with experimental results whenever appropriate. For example: “PSpice
simulation of the Colpitts oscillator of Fig. 6 indicates that a transconductance of 0.010
S is required for the circuit to become a self-sustaining oscillator. An experimental value
of 0.014 S was found. One possible explanation for the discrepancy may be that the
inductor Q was lower than estimated, resulting in a lower effective load resistance than
the value of 2400 used in the PSpice simulation.”
VI.
CONCLUSIONS
(1 POINT)
The conclusions will summarize the experiment and briefly describe how the results
address the objective(s) of the experiment.
