So, now we have gone through the basics of CMOS design. By now, we have also had one quiz illustrating some of the trade-offs and design parameters behind simple amplifier design. In the lessons, you have further looked at swing, cascodes, multi-stage amplifiers, etc. The three lectures and the three lessons have been a bit mutually exclusive to cover a fair amount of CMOS design.
Essentially, we have repeated the background required for the rest of the course. For some of you, this is new material and for some of you we have presented a different view of material you might already have studied. There could be some frustration, but it will become clearer as we throughout the rest of the course will relate back to all these parameters/design issues, etc.
By now you should know the following:
- How to find the input/output swing for amplifier stages.
- Derive the small-signal schematics
- Understand the basics of feedback and stability and relate these to amplifier design at the first level of abstraction.
- Common-gate, common-source, common-drain, current-mirror
- Compensation techniques
- Concepts for OTA/OP
Next lecture is on switched-capacitor circuits (1.5 weeks from now). The lecture after that will repeat some OTA design such that they can be used for filter and data converter design.
