That is, what does it do?
Looks like a current-output op-amp with a single-ended output (source,
very limited sink. At least, the three output transistors look like a
servo'd current mirror, with MP1 and MP2 providing the differential
capability.
Only half of this actual IC cell is shown (for proprietary reasons),
but power consumption of the total cell is 1.37uA.

Aren't 3904s noisy as hell?
Hmmm...

"Mirror, mirror upon the wall,
Who is the noisiest noisy of all?"

What, pray tell, do "3904s" have to do with a CMOS circuit?


Don't know but my comment can be read at different levels :-)
