Instructor: Professor Michael Flynn
This course is an introduction to CMOS analog and mixed signal design, but also introduces advanced topics. The course begins with a review of MOS transistors basics, and small signal analysis. Single stage and differential amplifiers are described. CMOS opamps, stability, and frequency compensation are covered. Advanced topics such a switched capacitor circuits may also be covered, time permitting. This course includes a major design project. Students work with a commercial 0.13µm CMOS process. A full suite of commercial design tools from Cadence is used for schematic entry, simulation and layout. (The tools and process technology are close to the state-of-the-art for analog design). Students will have the opportunity to send the best design projects to be fabricated through the MOSIS IC prototyping service (www.mosis.org) Taken alone this course is a good foundation in analog / mixed-signal design. This course is a prerequisite for EECS 511 (analog to digital converters and interfaces) EECS 522 (analog and RF circuits). It also satisfies course requirements of the Circuits and Microsystems, VLSI and E&M majors.
