Hi, List.

I am working on a mixed signal system and I need to generate a smallish 
negative voltage, (say -1V or so) for use as a negative op 
amp/comparator supply to overcome problems like comparators not swinging 
to ground, etc.

In the past, I have used ICL7660's or National LM2687, both work well; 
solid enough and quiet enough, but they seem like overkill....does 
anybody have a favorite, simple solution for something like this?

Thanks,
