Department Notes:

Course objectives: To give the student a firm grounding in the analysis and design of MOS and bipolar analog integrated circuits. Emphasis is placed on the practical aspects of IC design, and on intuitive understanding of circuit behavior as opposed to heavily analytical approaches. A heavy emphasis is placed on design content, and the students use SPICE as a simulation tool.

Topics covered:

  • Single-stage amplifier configurations with emphasis on MOS, other technologies (e.g. BJT) for comparison
  • Multi-stage amplifiers, cascode, Darlington connections
  • Differential pairs, differential and common mode responses, common-mode rejection
  • Transistor current sources, current mirrors, cascading
  • Supply and temperature independent biasing and references
  • Frequency response
  • Parasitic capacitances in transistors
  • Bode plot
  • Gain-bandwidth product
  • Approximation techniques and the zero-valued time constant approach
  • Feedback concepts
  • Series and shunt configurations
  • Feedback network loading
  • Gain desensitization and input/output impedance modification
  • Analysis of general purpose single and multi-stage transconductance and operational amplifiers
  • Stability, phase and gain margin
  • Compensation of amplifiers with feedback, pole splitting
  • Slew rate in operation amplifiers
  • Role and use of CAD tools such as SPICE in design process
