I was particularly impressed in this webinar, and the subject of thermal
noise generated by resistors in an analog circuit. I'd forgotten that
resistors with higher values contribute more thermal noise.

Depends on whether noise voltage or current is the dominant effect in that part of the circuit. Bipolar transistor current mirrors are noisy, but adding large emitter resistors makes them quieter...
