Abstract

According to some implementation, a charge pump includes a boost charge pump circuit and a buck charge pump circuit sharing a common flying capacitance. In some implementations, the boost pump circuit includes an input node and a boosted-voltage output node, and the buck charge pump circuit includes the input node and a divided-voltage output node. In some implementations, the charge pump of claimwherein the boosted-voltage includes 2×Vin, and the divided-voltage includes Vin/2, Vin being an input voltage at the input node. In some implementations, the boost pump circuit further includes a first holding capacitance that couples the boosted-voltage output node to a ground. In some implementations, the buck pump circuit further includes a second holding capacitance that couples the divided-voltage output node to the ground.
