Course Goals

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

Instructional Objectives

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 bipolar and MOS transistor models. (a,m)

2. Estimate driving-point small-signal resistance using four resistance reflection rules. (a,k,m)

3. Identify three basic amplifier configurations: common emitter (source), common base (gate) and common collector (drain). Handle bipolar and MOS transistors with emitter (source) degeneration. (a,k,m)

4. Understand and estimate the gain and input/output resistances of two-stage amplifiers from nine possible combinations. (a,k,m)

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

6. Design current sources and mirrors for integrated circuits including such sophisticated topics as supply- and temperature-independent biasing circuits. (c,k)

7. Design a band-gap reference generator. (c,k)

8. Perform DC and AC analysis of the standard operational amplifier and understand high performance operational amplifier design for low offset, low input current and low offset drift. (a,k,m)

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:

9. Understand the gain-bandwidth concept and frequency response of the three basic amplifiers. (a,m)

10. 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. (a,k,m)

11. Apply the Nyquist stability and use the Bode plot to estimate the phase margin of operational amplifiers in feedback. Understand operational amplifier frequency compensation. (a,k,m)

12. Estimate the transient settling time of amplifiers and understand the slewing and settling behaviors. (a,k,m)

13. Design high-performance operational amplifiers with high slew rates and understand other variations in the operational amplifier design in both CMOS and bipolar technologies. (c,k)

14. Identify circuit noise sources from active and passive devices and handle noise power spectral density. (a,m)

15. Estimate circuit noise density, minimum detectable signal and noise figure. (k)
