Abstract
A hybrid charge pump including a hybrid circuit configured to snub an over shoot or under shoot present in an input pulse in a snubbing operation if a level of the pulse is a first level, store the pulse in a charging operation if the level of the pulse is a second level different from the first level, and generate a negative voltage from the stored pulse in a negative voltage generation operation.
