Abstract
A charge pump structure and integrated circuit device. The charge pump structure includes a first stage charge pump unit implemented with low voltage devices that raises an input voltage using a system clock signal; and a plurality of second stage charge pump units, each implemented with low voltage devices that raise an output voltage of a prior charge pump unit using one of a series of boosted clock signals.

A charge pump structure, comprising:
- a first stage charge pump unit implemented with first stage low voltage devices that raises an input voltage using a system clock signal;
- and
- a plurality of second stage charge pump units, each implemented with second stage low voltage devices that raise an output voltage of a prior charge pump unit using one of a series of boosted clock signals, wherein the second stage low voltage devices have a different voltage rating than the first stage low voltage devices.
An integrated circuit (IC) device, comprising:
- a charge pump that includes:
- a plurality of staged charge pump units each having low voltage devices;
- and
- a plurality of boosted clock signal generators;
- wherein each charge pump unit increases an output voltage of a prior charge pump unit using a boosted clock signal generated from one of the plurality of boosted clock signal generators.
