Objectives: This course is intended to develop the understanding of analog bipolar integrated-circuit design. Students who have successfully completed this course should:

  1. be able to explain the hybrid-pi model of the bipolar junction transistor,
  2. be able to analyze and design amplifier, current-mirror, and output-stage circuits,
  3. be able to analyze the operation of an operational amplifier at the transistor level,
  4. be able to use the Miller effect to find the bandwidth of a circuit
  5. be able to use time constants to obtain an estimate of the frequency response of a circuit
  6. be able to use the return ratio to analyze circuits with negative feedback
  7. be able to determine the gain and phase margins of a negative-feedback amplifier
  8. be able to design a simple compensation scheme to stabilize a negative-feedback amplifier
  9. know how to use SPICE to find the characteristics of amplifiers, current mirrors, and output stages, and
  10. be able to use laboratory equipment including signal generators and oscilloscopes.

Laboratory Assignments: The 110b lab consists of eight experiments and is held in 2157 and 2161 Kemper Hall. The lab instructions can be downloaded (see the PDF files below). The tentative lab schedule is shown below.
