Course Description:

Analog Electronics – SC412 - is a continuation of SC410. Topics include differential amplifiers, frequency response, feedback principles, multi-stage circuit design, operational amplifier structure and design, bipolar, MOSFET, CMOS, and BiCMOS design principles, power amplifiers, active filters, and oscillators. (4 credits)

Prerequisites: SC410

Text: Microelectronic Circuits and Devices, 2^nd edition, M. Horenstein, Prentice-Hall, 1996.

Lab Manual: Laboratory Manual for Electronics, Moe Wasserman, Prentice-Hall, 2002.

Course Methodology:

The course involves the use of a coordinated set of lectures, analog circuit labs, a lab project, homework, and exams to teach analog electronics to undergraduate students at the junior/senior level. In addition to the lectures, separate discussion sessions are set up with the GTF for small-group discussion of homework problems/solutions, laboratory experiments, and review of the lecture material. The labs and project reinforce the subject material from the lectures and text with hands-on breadboard-type construction of various op amps, differential amplifiers, power amps, active filters, and oscillators. Homework is assigned from the problem section of each chapter covered in the text.

Laboratory: You must be registered for a laboratory section.

Discussion Sessions: Three weekly 1-hour discussion sessions will be set up at the convenience of students and the GTF.

Grading: Mid-term Exams 20% each

Final Exam 25%

Labs 10%

Lab Project 15%

Homework 10%

Design Project:

A Laboratory Design Project will be assigned during the week of March 3^rd. The demo and critique of the projects will be scheduled during the week of April 28^th, the last week of the semester. You will work in teams of 3 or 4 students each. The Project will give you an opportunity to do real design work and should make the extra effort required worthwhile.

Rules for the SC412 Laboratory:

All students are to purchase a bound 8½ x 11 lab notebook and put all relevant data in it. Please do not use loose-leaf data sheets in the laboratory. If you purchased such a notebook for SC410 and have plenty of blank pages left, you may use the same notebook for SC412. You may also be required to write laboratory reports. You may work on your lab experiments in pairs, but will work in teams of 3-4 students each on the Design Project.

Course Policies:

1. Missed Exam – Absence from an exam can be excused only for reasons of illness, death in a family, or unavoidable travel. In each case, permission of the instructor in advance is required, as well as a written authorization by a physician (in the case of illness) or other appropriate authorized signature. The student will be required to take a makeup exam.

2. Late Homework – Late homework will be accepted up until the date the solutions are discussed in class. A penalty of 10% off per day will be applied. A weekend counts as a single day.

3. Late Labs – Late labs will be accepted, but with a penalty applied of 5% off per day. It is advantageous for students to complete all the labs. Again, a weekend will be considered as a single day.

4. Attendance – Attendance in class is considered essential and required. Pop quizzes will be given on occasion with the opportunity to earn extra credit points by taking the quiz. Makeup quizzes will not be given.
