Abstract
An voltage regulation apparatus for generating a supply voltage internally within an integrated circuit with a modular arrangement of charge pumps. The charge pumps feature a first plurality of parallel-connected blocks of charge pump stages including a first block of charge pump stages, a last block of charge pump stages, and at least one intermediate block of charge pump stages therebetween. Each of the parallel-connected blocks of charge pump stages includes a group of a second plurality of charge pump stages cascade-connected in series; and an output stage connected to an output node. Desired output voltages are obtained by using combinatorial clock signals, generated by a logic circuit, directed to the various charge pump stages.
