**Prerequisites by Topic:**

- Analog electronic circuit analysis (EE 332)
- Analog simulator proficiency (SPICE)
- Electronic device modeling (MOSFET and Bipolar)

**Topics:**

- Operational amplifier circuits (Franco Chapters 1 and 2) [2 weeks]
- Static op amp limitations (Franco Chapter 5) [1 week]
- Dynamic op amp limitations (Franco Chapter 6) [1 week]
- Noise (Franco Chapter 7) [1 week]
- Stability and compensation (Franco Chapter 8) [2 weeks]
- Nonlinear circuits (Franco Chapter 9) [1 week]
- Active filters (Franco Chapters 3 and 4) [1 week]
- Signal generators (Franco Chapter 10) [1 week]

**Course Structure:** The class meets for four lectures a week, each
consisting of 50-minutes. Homework is assigned weekly for a total of 9
assignments over the quarter. A comprehensive final exam is given at the
end of the quarter. Laboratory work constitutes a significant focus of the
class and is organized into smaller laboratory sections, typically 24 students
divided into 8 groups of 3 each, which meet weekly.

**Computer Resources:** HSPICE or PSPICE may be used for circuit
simulation; Mathcad or MATLAB may be used for general purpose mathematical
analysis; Filter Wiz may be used for filter design; SWITCAP may be used for
switched capacitor filter simulation; and National Instruments LabVIEW may be
used for computer controlled data acquisition and instrument control.
HSPICE, PSPICE, and MATLAB are available in all of the general purpose computing laboratories in
the EE Department. Filter Wiz and SWITCAP are distributed to the students
as needed. LabVIEW is available in the room 137 EE1 laboratory,
integrated with hardware for data acquisition and instrument control.

**
Laboratory Resources:** The main electronics laboratory in room 137
supports this class with benches equipped with oscilloscopes, power supplies,
function generators, digital multimeters, test leads, and computers equipped
with GPIB controller and data acquisition PCI cards. Laboratory parts
kits are available from the EE Stores, with sales of individual
components as needed for the design projects. Students often order
components of their own choosing from mail-order/web-based vendors.

**Laboratory Structure:** The laboratory consists of 3-4 major design projects
given across the quarter.
Examples of past design projects include:

- CV/CC regulated power supply
- Design of an active filter
- Design of a switched capacitor filter
- Design of a function generator
- Autoranging AC voltmeter
- Low noise biopotential amplifier
- Synchronous capacitance meter
- Digital atmospheric pressure meter and altimeter
- Photographic exposure meter and bar graph
- Wide range thermocouple digital thermometer

**Grading:** Laboratory Design Projects (60%), Homework (25%),
Final Exam (15%)

**Outcome Coverage: **__This course provides the ABET major design
experience and addresses the following outcomes: __

Outcomes:

(a) *An ability to apply knowledge of
mathematics, science and engineering.* The vast majority of the lectures,
homework and projects deal with the application of circuit theory to electronic
system analysis and design. Mathematical formulations are commonplace throughout
the course. (High relevance to course)

(b) *An ability to design and conduct experiments, as well as to analyze
and interpret data.* The course includes a weekly three hour session in our
undergraduate electronics laboratory. Laboratory experiments include analysis,
design, construction, and testing of specific electronic systems utilizing
transistors, resistors, capacitors, integrated circuits, etc. The performance of
each student in the laboratory is evaluated by the teaching assistant as part of
the laboratory grade. (Medium relevance to course)

(c) *An ability to design a system, component, or process to meet desired
needs within realistic constraints such as economic, environmental, social,
political, ethical, health and safety, manufacturability, and sustainability. *
Most of the homework problems and all of the laboratory design projects are
phrased in terms of realistic constraints such as cost, size, weight, power
consumption, alignment ease, component variation, and manufacturability.
(High relevance to course)

(e) *An ability to identify, formulate, and solve engineering problems.*
Both the homework and laboratory design projects involve a large component of
solving engineering problems. The laboratory design projects are
open-ended and additionally require the students to identify and formulate the
principle issues associated with the engineering problems. (High relevance
to course)

(g) *An ability to communicate effectively. *Students receive written
guidelines on proper format and writing style for laboratory reports on the
class homepage. For each of the design projects, each group is required to write a
laboratory report in the required format. The laboratory reports are graded for
writing style as well as technical content. (Medium relevance to course)

(i) *A recognition of the need for, and an ability to engage in life-long
learning. *This is a course on modern electronic circuit design. The systems
the students design are made up of integrated circuit components, resistors,
capacitors, etc. These building blocks change rapidly with time as new faster,
better, cheaper components replace older ones. The students recognize in a
direct way the rapid changes and the need to stay current in the field.
(Medium relevance to course)

(k) *An ability to use the techniques, skills, and modern engineering tools
necessary for engineering practice. *Students use many computer design aids
in this course. Industry-standard circuit simulators, PSPICE or HSPICE, are used
routinely throughout the course for homework and design projects. Mathematical programs,
such as Matlab or MATHCAD are used for higher level
calculations and simulation. Filter design packages such as FILTER WIZ are used for active filter
design, and the switched capacitor filter simulator SWITCAP is used for switched
capacitor network evaluation. Industry-standard LabVIEW is also used for
laboratory data acquisition and instrument control. (High relevance to
course)

**ABET Criterion 4 Considerations**

*Engineering standards* - Students must develop their laboratory design
projects to meet specific performance specifications, some of which include
benchmark testing or compliance testing against accepted standards for
performance and safety.

*Realistic constraints* - Each of the laboratory design projects, in
addition to having explicit electrical performance specifications, is
fundamentally phrased and graded in terms of the final solution's size, weight,
cost, power consumption, alignment ease, component variability, and
manufacturability criteria.
