Analog Integrated Circuits

The first sessions of the course are devoted to the reminders of large and small signal transistor models as well as to the techniques of small-signal modeling of elementary analog integrated circuits. The second part is devoted to the description of the basic blocks whose interconnection allows the realization of analog integrated circuits: current/voltage reference, mirrors and current sources, amplifiers with active load to a transistor, differential pair. The fundamentals of CMOS amplifier design are discussed in Part Three. The focus is on the performance-sizing linkage of transistors as part of the design of a two-stage Miller amplifier. Some advanced amplifier architectures are presented at the end of the course in order to highlight the interest of mastering the basic blocks.
