Course Objectives Basic knowledge of semiconductor devices and microelectronic circuits is assumed, as presented in ECEN 3250. Starting from this background, the course objectives are to introduce principles of analog integrated-circuit analysis, modeling and design. With the emphasis on CMOS technology, basic device models are reviewed and developed further to cover sub-threshold and short channel effects, as well as device parasitic capacitances. Integrated-circuit dc biasing techniques are presented starting from simple to more complex current mirrors, leading to analysis and design of current and voltage references. Temperature and power supply sensitivity, as well as absolute and mismatch parameter variations are introduced. Integrated-circuit amplifier realizations are studied, starting from a review of basic gain stages, leading to analysis and design of operational amplfiers and comparators. Frequency response limitations are addressed through the zero-value time constant method and the extra-element theorem. In the context of operational amplifiers, feedback, stability and compensation topics are introduced. Students learn how to use simulation tools to verify integrated-circuit designs across process and temperature corners.
