Office Hours: Thursday 03:30 PM – 5:00 PM

**Prerequisites**

Electronic Devices & Circuits

**Course Overview**

This course is an introduction to the fundamentals of microelectronic circuits.

The topics include modeling of microelectronic devices, basic microelectronic circuit analysis and design, power amplifiers, operational amplifiers circuits, frequency response of amplifiers, feedback amplifiers and oscillators.

Students will receive an assignment every week, which will cover the topics discussed in the class in that week. All the assignments must be completed and turned in by the Tuesday of the week following the one in which they are posted. No late assignments will be accepted.

The course will also have a quiz in every lecture, a midterm and a final exam.

**Course Objectives**

After this course, students should have a strong intuition and insight of the various discrete and integrated amplifiers, which can be further used to design and optimize circuits’ performance. This includes the modeling, biasing, gain and frequency response of such amplifiers. Operational amplifiers and its circuits should be in the grasp of the student.
