Analog CMOS Circuits

Lecturer: Kent Lundberg
Covers the analysis and design of analog circuits in CMOS technology. The first half of the course includes coverage of fundamental material, such as MOS transistor device modeling, simple sub-circuits, and device noise theory. The design of operational amplifiers in CMOS is covered in detail, and the course concludes with a discussion of analog filter design. The second half of the course covers the design of switched-capacitor circuits, comparators, digital-to-analog and analog-to-digital converters, oscillators, and phase-lock loops.
