Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A hybrid charge pump comprising: a hybrid circuit configured to, snub an over shoot or under shoot present in 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, wherein the first level includes a logical low level, and the…
