Course Description: This course is an introduction to electronic circuits. It applies concepts from ECE201 to circuits with active devices (transistors). The important concept of an equivalent circuit model is stressed, and students are introduced to silicon microelectronics. In addition to analysis of electronic circuits, the course stresses design, solving open-ended problems and the use of computer tools in the design process.


Homework: Homework will be assigned weekly and is due at 5:00 pm. on the due date in the Homework DropBox located in MSEE 180. Include your name and student ID number on each page. (If you prefer more privacy, just write the first letter of your last name followed by the last four digits of your student ID number.) Homework will be returned to you in class a week later. 


Be sure to clearly identify the final answer in each homework problem by drawing a box around it. Include units in your answers and only the appropriate number of significant digits. For SPICE homework problems and projects, the assignment sheets will provide detailed instructions regarding the calculations, graphs, and other material which must be turned in.



Homework and Quizzes – 100 pts

SPICE Designs (Required) – 100 pts

Exam 1 – 100 pts

Exam 2 – 100 pts

Exam 3 – 100 pts

Final Exam – 150 pts


Course Policies:

         Cheating on exams or assignments will result in a grade of zero for that exam or assignment. All cases of cheating will be reported to the Assistant Head of the School of Electrical and Computer Engineering and to the Office of the Dean of Students. When the end of an exam is announced, students who fail to cease working and to hand in their exams immediately will be assumed to be cheating.

         All ECE 255 course work must be done individually. We encourage you to discuss and collaborate on ideas for doing the homework, but what you hand in should be your own work. Do not read another student's solution or allow yours to be read.

         Homework solutions will be placed on the ECE 255 web page.

         There will be NO written make-up exams. If you cannot avoid missing an exam (and have supporting documentation), contact yout instructor BEFORE the exam and we’ll work something out (e.g. an oral exam).

         We will assume that you have read the assignments BEFORE coming to class (see the schedule posted on the website).

         Come to class ON TIME.

         We encourage you to use e-mail to communicate with us. You’ll probably find it easier to get short questions answered by e-mail rather than during office hours. 

         Constructive comments are always welcome on how the course can be improved. 



Brief Course Outline

Weeks   Topics
1-3 Diodes and the concepts of mathematical and equivalent circuit models. Applications of models to circuit analysis and design. Introduction to the Spice computer program.
4-6 Bipolar transistors (BJTs), dc and ac models and the use of these models in C-E amplifier design.
7-9 MOS transistors (MOSFETs), dc and ac models and the use of these models in C-S amplifier design.
10-11 The analysis and design of other small signal amplifier configurations.
12-13 High frequency transistor models and the frequency response of small signal amplifiers.
14 Multistage amplifiers, currents mirrors, and differential amplifiers.
15 Topics for the last week are selected by the instructor.


Ethics in ECE 255 

Along with the rest of the ECE faculty, we expect every member of the Purdue community to practice honorable and ethical behavior both inside and outside the classroom. Any actions that might unfairly improve a student's score on homework, or examinations will be considered cheating and will not be tolerated. Examples of cheating include (but are not limited to):

                     Sharing results or other information during an examination.

                     Bringing forbidden material or devices to an examination.

                     Working on an exam before or after the official time allowed.

                     Requesting a regrade of answers or work that has been altered.

                     Submitting homework that is not your own work.

                     Reading another student's homework solution before is it due.

                     Allowing someone else to read your homework solution.

Cheating on an assignment or examination will result in a reduced score, a zero score, or a failing grade for the course - at our discretion depending on how we judge the severity of the incident. All occurrences of academic dishonesty will be reported to the Assistant Dean of Students and copied to the ECE Assistant Head for Education. If there is any question as to whether a given action might be construed as cheating, see us before you engage in any such action.







   In the event of a major campus emergency, course requirements, deadlines, and grading percentages are subject to changes that may be necessitated by a revised semester calendar or other circumstances. In such an event, information will be provided through this website and/or Blackboard.
