Abstract
A charge pump system can provide multiple regulated output levels, including several concurrently, in an arrangement that can reduce the area and power consumption of such a high voltage generation system. The charge pump system can be dynamically reconfigurable based on output requirements. When output level is low, but required for a large AC, DC load, the system is configured in parallel to share the load. When a higher output is required, such as for a programming in a non-volatile memory, the system is configured in serial to generate the desired high output level. The exemplary embodiment uses all of the pump units in each operation and, hence, is able to be optimized for smaller pump area and less power consumption, while still delivering the same pump ability as larger, more power consuming arrangements.
