As homework, i should design a transimpedance amplifier (with opamp)
for photodetector's front end. I haven't any specification about
photodiode's characteristics, so i haven't any information about
pratical uses of this system. I can choose arbitrarily any photodiode
and hence any application: so i'm looking for any application note,
data sheet, reference regardings pratical (and simple) applications.
I'm particurlary interested in gas sensing or any domotic application
(except light sensor)...any ideas?
thanks in advance

Please look up "cross posting" on Wikipedia, and check the difference
between it and "multiple posting". Then please use USENET wisely.

While you're at it, consider using a real newsreader. By your email
account you're posting from Google, Google is making no efforts to
reduce spam from their service, so many folks just block anything coming
from google, or with a gmail account.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
