Abstract
The diode drops associated with the output voltage from a conventional charge pump are eliminated in the present invention with a dual-chain charge pump that utilizes the pumped voltages from each charge pump chain to drive the gates of the other charge pump chain. As a result, the voltages on the gates of the transistors are pumped up to a level such that there is no threshold voltage drop across the transistor, and thus, making it behave like an ideal switch.
