includes circuit simulation computer (PSPICE) projects. There are
five laboratory experiments including an extensive design project
with a formal written report. There will be two midterms and one
final in class examination.

**Computer Resources:** PSPICE on PCs for circuit
simulation. MathCad or MATLAB for circuit analysis.

- Single transistor amplifiers
- Differential pair amplifiers
- Output stages
- Design project (multi-week, open ended)

**Grading: **Weights given laboratory reports (1), each midterm examination
(1), design project (1), homework (0.5), and final examination
(1.5)

**Outcome Coverage:**

(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. (H)

(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.
(M)

(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.* Several of the homework problems and the design project
require designing circuits to meet stated specifications. Other problems
and experiments require meeting specific voltage and current drive
requirements. (M)

(e) *An ability to identify, formulate and solve engineering
problems.*
The homework involves solving engineering problems identified by the
assignments and exemplified by class discussion. The midterm and final
projects challenge the students to identify the issues and formulate
their individual solutions. (M)

(g) *An ability to communicate effectively.* Students are required to
submit written reports describing the final design project; they are
encouraged to present their solutions during the weekly problem
sessions. (M)

(h) *The broad education necessary to understand the impact of
engineering solutions in a global, economic, environmental and
societal context.* Analog semiconductor chips have become pervasive in
almost every product we buy. In reviewing the societal impact of the
increased complexity and lower cost of modern silicon analog
integrated circuits and devices, we also discuss the potential for
future improvements, and consider the changes that may result from
them. (L)

(i) *A recognition of the need for, and an ability to engage in
life-long learning.* The course emphasizes basic fundamentals that are
applicable to the analysis and design of analog integrated circuits.
As performance parameters increase dramatically with rapid scaling of
technologies employed in the fabrication of ICs, there is a need for
the professional to maintain state-of-the-art knowledge of the
relationships between device and circuit performances. (L)

(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. The circuit simulator, PSPICE, is used
along with its post processor PROBE. The mathematical program MATHCAD
(or MATLAB) is used for high-level mathematical calculations. (H)
