ELEC 3215 - Electronics I The learning objective is fundamental semiconductor theory as applied to electronic circuits. Topics include: semiconductor theory, P-N junctions and diode applications, power supply design, transistor (BJT) theory and applications, low-frequency amplifiers, FET and MOSFET devices. Prereq: ELEC 2132, PHYS 2331 and CHEM 1130. ELEC 2142 - Circuit Analysis II Sequential course after ELEC 2132. Topics include: Solution of circuits using Laplace transforms, frequency domain analysis, additional steady-state solutions, Bode plots, active filters, pulses, impulses, and computer-aided analysis. Prereq: ELEC 2132, MATH 2421, PHYS 2331. Instructor Description: To design modern electrical engineering systems, a good fundamental understanding of analog electronics is essential. While it is true that discrete device designs constitute only a small portion of electrical engineering these days, the mathematical modeling techniques and problem solving studied in the course is universally applicable. "Where there is Intelligent Design, there is an Intelligent Designer" In memory of Marv Anderson Course Objectives: Before one can begin to tackle the problems associated with high speed, high power or VLSI circuitry, one must have a good understanding of the basic principles of solid state devices. In this course, basic amplifier configurations are studied. The goal is to understand the following: 1) Analysis, bias and design of single stage BJT and JFET amplifiers. 2) Analysis, bias and design of differential amplifiers. 3) High gain amplifiers. 4) Frequency response limitations of amplifiers. 5) Feedback amplifiers and oscillators.

Assignments and Examinations: Assignments – Homework will be due 1 week from the day assigned unless otherwise announced in class. Homework scores will not be numerically interpreted for the final grade. Instead, homework scores will be used to determine the final grade in the case of an average score which is borderline (i.e. 88 or 89 would be an “A” with good homework performance). . Examinations – The Midterm exam (closed book) will be week of March 7. Final Exam – Scheduled by AHEC the week of May 7. Assessment Design Grades: Final grades will be based on the following: Midterm (20% take home, 80% in class): Final (20% take home, 80% in class): 30% 40% Computer Design Projects (2 or 3): Homework: Attendance and professional conduct: 20% 10% 10% Course Policies: Class attendance is expected of all students. Students are responsible for any material they missed. All grading will be done on an absolute (straight line) scale. Graded work will be returned in class. Late work may incur a penalty and will not be returned at the same time as the rest of the class. Teamwork on homework and computer projects is encouraged. However, all work submitted must be individual – duplicate computer files or copied homework will not be accepted. Academic conduct and accommodations shall be consistent with university policies. Cell phones must be turned off and put away during all exams. 2 Course Schedule I. Introduction to Electronics II 1 period II.
