Grading: Regular grades are awarded for this course: A B C D E

Course Fee: \$100

Prerequisite(s):
ECE 351C
Textbook(s):

Sedra, Adel S., and Kenneth C. Smith. Microelectronic Circuits. 7th ed. Oxford University Press, 2015.
Herniter, Marc E. Schematic Capture with Cadence PSpice. 2nd ed. Prentice Hall, 2002.

Course Learning Outcomes:

Students completing this course should be able to design and use basic analog building blocks and understand how they interact using the operational amplifier as an example. The emphasis in the lectures is on developing recognition of the interplay between large-signal and small-signal behavior, on learning the constraints each place on the other, and upon using multiple stages to circumvent these problems.

Specifically, students should be able to:

1. Design a current mirror to meet specified compliance voltage, AC ripple requirements, and so on
2. Design differential amplifiers using active or resistive loads to meet large-signal swing and small-signal gain specifications
3. Design output stages to meet power delivery, efficiency and heating specifications
4. Relate capacitance in devices to the frequency performance of circuits, including the Miller effect
5. Use multiple stages (like the cascode, or voltage follower input and output stages) to avoid frequency limitations
6. Design a cascade of differential amplifiers that meets large signal and gain requirements
7. Use the methods of open- and short-circuit time constants to estimate bandwidth
8. Determine the loop gain of a feedback amplifier using return ratio
9. Determine the loaded gain of a feedback amplifier using two-ports
10. Design the four types of amplifier (voltage, current, transconductance and transresistance) based upon two-port theory and T-section resistor feedback networks
11. Relate feedback to frequency performance and stability using Bode plots
12. Design a stable circuit using Miller compensation
13. Design circuits to work for a range of device parameter variations
14. Build working circuit prototypes
15. Test and troubleshoot a prototype
16. Keep lab notebooks using standards required for use in a patent dispute
17. Write clear technical reports that meet professional standards
18. Use a variety of measurement instruments and techniques
19. Work closely with a colleague
Class/Laboratory Schedule:

Three 50-minute lectures per week
One 170-minute lab session per week
