Abstract
The charge pump generates high voltages for integrated semiconductor circuits. The charge pump has a plurality of pump stages with at least one power transistor each for generating a pump voltage on a power path. The power transistor has a freely switchable bulk terminal with which a well structure of the power transistor can be maintained at a predetermined potential via a well charge path that is substantially separate from the power path.
