Abstract

See full text

In a charge pump circuit, a first circuit is configured to provide a first node with a first first-voltage level or a first second-voltage level. A second circuit is configured to provide a second node with a second first-voltage level or a second second-voltage level. The first node is coupled with a first end of a first capacitive element. The second node is coupled with a first end of a second capacitive element. A first end of a first voltage transfer circuit is configured to receive an input voltage. A second end of the first voltage transfer circuit is coupled with a second end of the first capacitive element and a first end of a second voltage transfer circuit. A second end of the second voltage transfer circuit is coupled with a second end of the second capacitive element, and is configured to provide an output voltage.
