Goals: This course aims to introduce the main elements of analog electronics starting from differential amplifiers. Multistage amplifiers, frequency response of amplifiers, output stages, feedback concept and oscillators are covered. Both bipolar and MOS transistor realizations are to be discussed.

Learning Objectives:

At the end of this course, students will be able to:

1. Analyze a given circuit such as differential amplifier or a multistage amplifier for input/output impedances or gain.
2. Analyze a given BJT or MOS circuit to find low and high cut-off frequencies.
3. Analyze a given BJT or MOS feedback circuit
4. Design a BJT and MOS amplifier with the given gain or impedance spsecifications
5. Design a BJT and MOS amplifier with the given cut-off frequency specifications

Course Structure: The class meets for four lectures a week, each consisting of two 50-minute sessions. There are one problem session meeting a week and additional 6 meetings for designing circuits and simulating them on SPICE. 2-4 Homeworks are given. There are two in-class mid-term exam and a final exam.

Computer Resources: There are 6 meetings. Circuits are simulated on SPICE

Laboratory Resources: None.

2. Midterm (25%)
3. Assignments/HW (15%)
4. Final (35%)

Outcome Coverage:

• Apply math, science and engineering knowledge. Basic tools from mathematics such as linear algebra, exponential functions, linearization and approximation techniques.

• Design a system, component or process to meet desired needs. Designing Bipolar junction transistor and MOS transistor multistage amplifiers which need the given specifications. For example to design an amplifier with a specific voltage swing and voltage gain. Similarly design of an amplifier with certain input and output impedance but simultaneously satisfying bias point restrictions. Also designing amplifiers for a given high or low frequency cut-off point.

• Use of modern engineering tools. Students use SPICE Simulator in assignments.
