Analog IC Design

About the course

Analogue Circuit Design introduces the students to the building blocks of the an Analogue Circuit. We will design analogue circuits in a CMOS process by calculating the required properties of various transistors. We will start by analysing single transistor circuits and calculate its performance parameters. We are primarily interested in using MOSFET Devices to build complex large analogue systems. We will also understand signal amplification and limitations of real world amplifiers. During the course, the student will learn to calculate and analyse the effects of noise in electronic circuits. We will also design, build and test filters to reduce the effect of this noise. Finally, we will learn to design simple data converters to convert analogue signals to digital and vice-versa
