ECE 203 - Lecture 16: Low-Power Voltage, Current, and Timing References

Lecture 16 in UCSD's course on Biomedical Integrated Circuits and Systems.
In this lecture we cover the basics of how to build voltage reference generators and current reference generators to bias amplifiers and other analog components. We start with some simple concepts and build up towards bandgap references. Then we discuss how to operate such circuits at low voltage and low power levels. We end the lecture with a discussion on low-power relaxation oscillators.

Fantastic presentation. Thanks for sharing.

Very well-presented video! I'm trying to build my own lab bench supply, and i think the Brokaw Cell might be just what i needed!

30:30 I think it should be Jc1 = m*Jc2, since current is same & Q2 is m times larger, it's current/area must be m times smaller. I know the numbers were just mistakenly reversed.

I love this stuff, I wish I could have worked in the semiconductor industry.

You still can?

You can 😊

Thank you, for the circuits in the 29min clock, why NMOS M1 and M2 needed?
