Charge pump circuit basis! (not in PLL)

[iamxo]

Does anyone suggest me some basic charge pump circuit or papers to realize above VDD and below gnd rail?

it's used for rail to rail input operation.

Thank you all very much.

using switch and caps, charge and discharge.

See the paper below from University of Toronto. A very basic theory about charge pumps.
