Degree Level

Analog Circuits

This course is an introduction to the analysis and understanding of transistor-based amplifiers. Students will first be introduced to basic concepts of MOS and BJT transistors, techniques for biasing them, and small-signal analysis fundamentals. This will then be extended to amplifiers, and their small- and large-signal characteristics. Frequency compensation techniques to stabilize higher order systems will be discussed. Noise in analog circuits will be introduced, analysis of noisy circuits will be studied. At the end of this course, students should be able to recognize and analyze the basic amplifiers and biasing arrangements using MOS or bipolar transistors. Students should also be able to perform dominant-pole compensation of higher order analog systems and stabilize them.
