I have had a mental block on which is which since I first ever read the words anode and cathode. > AC amplifier: no aplification factor is mentioned, so I'd offer either a > single capacitor between in put and output (factor ~1) or between output > and ground (factor ~0).

It's extremely rare that in this day and age anyone will need to draw a discrete amplifier especially having "good temp. stability" without looking at a book. I don't like closed book tests for this application. If you really want to see resourcefulness and ingenuity which is what you probably want from an employee you should give them a more difficult test and a stack of books. - MK -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
