Abstract:

The present subject matter relates to charge pump devices, systems, and methods in which a first plurality of series-connected charge-pump stages is connected between a supply voltage node and a first circuit node, wherein the first plurality of charge-pump stages are operable to produce a first electrical charge at the first circuit node, the first electrical charge having a first polarity; and a second plurality of series-connected charge-pump stages is connected between the supply voltage node and a second circuit node, wherein the second plurality of charge-pump stages are operable to produce a second electrical charge at the second circuit node, the second electrical charge having a second polarity.
