Analysis and Designs of Analog Circuits

Semester 2

The purpose of this course is to introduce the student to the fundamentals of the analysis and design of analog circuits. It continues on the basic concepts of operational amplifiers, diodes and DC transistor circuits that were explored in ELET1400. Topics to be covered include circuit application of solid state devices to the designs of various diode and transistor circuits. The differential amplifier and its use in the design of operational amplifiers are discussed. The students are also introduced to the functional operation of commonly used linear ICs along with the basic concepts of oscillations. The course ends with some examples of data conversion circuits that demonstrate the operational relationships between analog and digital circuits.

The use of manufacturers’ data sheets for the design of analog circuits is an integral part of this course. The learning experience is enhanced with computer-based exercises and assignments. The assignments will include: (1) a take home problem solving questions design to test student understanding of the theory; and (2) a report in the form of an IEEE paper structure on a survey of the state-of-the-art in analogue circuit designs. The intent is to expose the student to high level technical publications. Circuit simulation tools will be used throughout this course.
