Hi,

if it is fast varrying, try a votage doubler with germanium diodes like OA79, etc, the output can be clamped by three silicon diodes to fgive you around 3XVf of the diodes. this provided the variation is equal at MIN and MX.

otherwiase try MAX1724. it is said of capable of working from 0.8V. Datasheet at
