Timing and Structure

Michaelmas term. 16 lectures (including examples classes and case studies). Assessment: 100% exam

Prerequisites

3B1, 3B2, 3B5 assumed; 3B3, 3B6 useful

Aims

The aims of the course are to:

  • provide a firm foundation and problem-solving skills for students to design and analyze complementary metal oxide semiconductor (CMOS) analog circuits.

Objectives

As specific objectives, by the end of the course students should be able to:

  • have developed an awareness of the requirements in designing circuits in IC technology.
  • understand how CMOS scaling affects analogue circuit design.
  • design current sources and biasing stages of multi-stage amplifier circuits.
  • demonstrate a knowledge of the factors limiting high frequency behaviour of circuits.
  • design and analyse integrated operational amplifier circuits.
  • understand noise sources in circuits and compute signal to noise ratio and equivalent input noise.
  • demonstrate knowledge of the effect of feedback on circuit operation and stability.

Syllabus

The purpose of this module is to provide firm foundation and problem-solving skills for students to design and analyze complementary metal oxide semiconductor (CMOS) analog circuits. It will cover the major aspects of the design and fabrication of analogue integrated circuits and is intended to make graduates become more competitive to a large industrial segment looking for circuit designers, especially those skilled in analog and mixed signal circuit design.
