Abstract
According to various aspects, a latch-type charge pump may include: an input node and an output node; a first charge storage and a second charge storage coupled in parallel to each other, a first switch coupled to the input node and a second switch coupled to the output node, wherein the first charge storage couples the first switch with the second switch; and a control circuit configured to control the first switch based on a state of the second charge storage, and to control the second switch based on a state of the first charge storage.
