EE 114: Analog Circuit Design
EE 114: Analog Circuit Design (Caltech). Instructor: Professor Ali Hajimiri. The subject of this course is the analysis and design of analog integrated circuits at the transistor level, with an emphasis on intuitive design methods, quantitative performance measure and practical circuit limitations. The course deals with analog circuits in which the information is represented by signals that are continuous both in time and amplitude. Circuit performance is evaluated by means of hand calculations and computer simulations. Topics include: review of physics of bipolar and MOS transistors, low-frequency behavior of single-stage and multistage amplifiers, current sources, active loads, differential amplifiers, operational amplifiers, high-frequency circuit analysis using time- and transfer constants, high-frequency response of amplifiers, feedback in electronic circuits, stability of feedback amplifiers, and noise in electronic circuits, and supply and temperature independent biasing.
