charge pump negative voltage

what do you mean by V+/V-? like +0.5V and -0.5V?
Must the reference voltage be 0V from the ground?

Check out ICL7660, 'Principles and Applications of the ICL7660 CMOS Voltage Converter' from Intersil.

Isn't this the same request?
why post the same question in different forms in seperate posts?
