Can I use small signal mosfets to rectify the signal instead of the
schottky diode? This would gain my half a volt because the mosfet
would have very low voltage drop once it turns on.
How about a germanium diode?


Would it be ok to bias the gate positive all the time (with a small
button cell 3 volt battery) and just treat the mosfet like it was a
diode??
If you are goin to use a small battery, why not use a small opamp!
CMOS opamp at 3V should take little power.
perhaps you could take power from the laptop par port?
