The attendance at the exercises is highly recommended, however not mandatory for the admittance to the exam. They are indeed essential for the understanding and provide valuable insight into the analog circuits design-flow.

Since the nineteen-seventies the advantages of digital circuits have led to predictions that everything would become digital. Such predictions appear to become reality today since the most important applications, such as telephony, mobile communications and high definition television adopt a digital approach.

This leaves the impression that digital circuits will simply replace analog circuits until the latter will totally disappear from the electronic systems we use. In reality, the pervasiveness of digital circuits has increased the importance of analog circuits for the simple reason that most digital systems need analog circuits to interface with the real world which is analog. Analog circuits, instead of disappearing, have expanded with digital circuits into new applications. Although analog circuits often occupy only a small fraction of the total area of an integrated circuit, their performance is critical in deciding the overall performance of the system. Analog integrated circuit design is therefore among the most sought after skills by the integrated circuit (IC) industry.

This course provides a foundation in the analysis and design of most commonly used analog integrated circuits in both bipolar and CMOS technologies.
