Analog Integrated Circuits

The first sessions of the course are devoted to reviewing large-signal and small-signal transistor models, as well as small-signal modeling techniques for basic analog integrated circuits. The second part is devoted to describing the basic blocks whose interconnection makes it possible to build analog integrated circuits: current/voltage reference, current mirrors and sources, single-transistor active-load amplifiers, and differential pairs. The fundamental principles of CMOS amplifier design are examined in the third part. Emphasis is placed on the relationship between performance and transistor sizing in the context of designing a two-stage Miller amplifier. Several advanced amplifier architectures are presented at the end of the course to highlight the importance of mastering the basic blocks.
