EE4525 Analog CMOS design II

The goal of this course is to introduce students to the design of advanced analog circuits in modern CMOS technology. Students will learn how to use basic building blocks, such as current mirrors and differential pairs, to build more complex CMOS circuits, such as two-stage amplifiers. At the end of the course, the students will be able to design and optimize a complex CMOS circuits given its specifications.

Covered topics:

  • Gain-boosting technique: principle; high frequency behavior and settling.
  • Basic sub-circuits: source-follower; current-mirror; differential pair; biasing.
  • Opamp architectures: simple opamps; cascoded structures; folded cascode; telescopic opamp;
  • Fully differential structures; common-mode feedback; design procedure.
  • Two-stage design: cascading two stages; the need for compensation; miller compensation; pole-splitting;instability; nulling resistor; when to use a two-stage.
  • Class-ab output stages: example 2-stage miller design; definitions of class-a; class-ab and class-b; requirements; various design examples.
  • Distortion: distortion in feedback; intermodulation distortion.
