Purpose

The class covers introductory topics in analog electronics. Together with ELEG312 it is the foundation for integrated analog circuit analysis and synthesis. The main goal is to present the students to the fundamental semiconductor components, in particular diodes and transistors, appropriate modeling and analysis techniques as well as basic analog circuit configurations and applications. At the end of the class, the student should be able to model, analyze and, to a certain level, synthesize circuits containing a few transistors.

General Contents

During the first part of the semester we will review, briefly, fundamentals of electric circuits, followed by a more detailed study of diodes from the system level perspective without entering into the domain of solid-state electronics. The second part of the course is devoted to the study of single and two-stage amplifiers using bipolar and CMOS transistors.

Prerequisites

Basic Calculus; ELEG205: circuit analysis techniques (KVL and KCL, superposition, circuit transformation, Thevenin and Norton equivalents), some of which we will review here; good level of algebra (always nice!)

Class Requirements

 Three mid-semester tests, biweekly homework, weekly quizzes (easy), and illustrative lab experiments constitute the workload for the class. No final exam.

The tests and quizzes are individual and closed book. The instructor will provide a help sheet for midterm tests and NO additional material is allowed during exams or quizzes, except for calculators when necessary. Any requests for make-up tests (midterm or final) will be subjected to university policy. No normalization (curving) will be applied to partial grades (quizzes, homework, labs or tests); only final grades will be normalized according to statistical distribution of data.

Theoretical homework and lab experiments are in groups of two people (you can work alone for the homework if you will, but the lab sessions have to be in couples). Only one homework submission per group is necessary and it is due at 5PM on the submission date (see schedule next page). Homework that is not submitted on the due date by 5PM will not be accepted, and will be assigned a grade of zero.

Quizzes are an easy and fast way to keep you focused on the subjects presented in class and covered in the homework exercises. I urge you to devote time to homework and quizzes and come back to class or office hours (TA’s or instructor’s) to clear your doubts  A good, well-distributed dedication to such simple matters will ease your way to the tests and guarantee satisfactory final grades. Quizzes and homework solutions, as well as test solutions will be posted shortly after their submission date (see schedule next page).

The worst personal quiz of the semester will not be taken into account in the grade computation. In addition, you have the possibility of one and only one “make up” quiz within one week of the original quiz date with no academic penalty. Any other quizzes missed during the semester will count as zero.

Attendance to lab sessions is mandatory and except for proven medical conditions the lab practices are not to be rescheduled or reprogrammed.

Important Note

Any evidence of copied lab reports, homework or dishonesty during tests and quizzes will result in an academic dishonesty report in your record and the corresponding academic penalty. NO EXCEPTIONS.

The grade distribution is as follows:

            3 Mid-term tests                                   45%

            Quizzes                                                            25%

            Homework                                           15%

            Lab                                                      15%
