Device for voltage multiplication with high efficiency, combination of the device with a battery-operated apparatus, and low-power loss generation of a programming voltage

摘要

The device for voltage multiplication on the basis of a boosted charge pump is used, for example, as on-chip high-voltage generator in EEPROMs and flash EEPROMs. As a result of charging the pump capacitances via tristate drivers and a simplified timing scheme, the power loss is reduced and chip area is saved.
