Course description [Click here for the course syllabus]

Design of analog integrated circuits using semiconductor transistors. Emphasis on intuitive, analytical, and simulation-based circuit analysis and design. Topics include:

* Theory of electrical conductivity; metals and semiconductors;
* The physics of semiconductors;
* Principles of pn junctions, bipolar transistors, and field-effect transistors;
* Bias circuits & active loads;
* Single- and multi-stage amplifiers;
* Operational amplifiers;
* Frequency response;
* Feedback and stability;
* The physics of noise processes;
* Noise analysis (input referred noise and noise figure);
* Switched capacitor circuits; comparators;
* Data coverters.

Grading policy

Grading will be based on homework & final project:

* Homework (70%): Homework problems will be on analysis, simulation, and design of circuits, often using Cadence Spectre with BSIM MOS transistor models. Your solutions need not be wordy, but you should detail your reasoning. If we can't figure out what you did, your points will not be high.

* Final project (30%): Project details will be handed out after about 2/3 of lectures are finished.

* Late grading policy: Each weekly set of homework problems will be handed out in class on each Thursday, due 2:00pm sharp next Thursday at the black drop box outside my office (Maxwell-Dworkin Room 131). Late work will be reduced 25% per week. There is no exception to this rule, other than University-established emergency cases (a letter from authorized official is required). This late grading policy will be strictly enforced for fairness to all.

* Cooperation policy: Collaboration is allowed, but you should turn in your own homework --- You can discuss any problem with other students taking the course, but final solutions should not be exchanged. You should make it sure that you understand the solution you turn in, and write up the solution in your own words. Basic guideline is not to take undue advantage of any other student.
