This course is a senior elective for electrical engineering majors. The goals are to introduce basic transistor circuit design concepts using CMOS, to give students practical design experience with design examples and to make electrical engineering majors ready for analog integrated circuit design tasks.

A. By the time of Midterm Exam (after about 20 lectures), the students should be able to do the following:

1. Understand the large and small signals and use MOS transistor models. (1)

2. Estimate driving-point small-signal resistance. (1,7)

3. Identify three basic amplifier configurations: common source, common gate and common drain and their derivates. (1,7)

4. Understand and estimate the gain and input/output resistances of two-stage amplifiers. (1,7)

5. Use two-stage amplifier configurations and understand the differential pair and its offsets and common-mode rejection. (1)

6. Design current sources and mirrors for integrated circuits (2,7)

7. Perform DC and AC analysis of the standard operational amplifier and understand high performance operational amplifier design for low offset, and noise. (1,7)

B. By the time of Final Exam (after 42 lectures), the students should be able to do all of the items listed under A and B, plus the following:

8. Understand the gain-bandwidth concept and frequency response of basic amplifiers. (1)

9. Estimate dominant pole frequencies using pole splitting Miller effect and the zero-value time constant method. Extend the concepts to understand the frequency response of operational amplifiers. (1,7)

10. Use Bode plots to estimate the phase margin of operational amplifiers in feedback. Understand operational amplifier frequency compensation. (1,7)

11. Estimate the transient settling time of amplifiers and understand the slewing and settling behaviors. (1,7)

12. Design high-performance operational amplifiers with high slew rates and understand other variations in the operational amplifier design. (2,7)

13. Identify circuit noise sources from active and passive devices and handle noise power spectral density. (1)

14. Estimate circuit noise density, signal to noise ratio. (7)
