Abstract
Various embodiments of the present invention relate to a voltage generator, and more particularly, to systems, devices and methods of configuring a charge pump system by incorporating an auxiliary charge pump to generate an intermediate voltage that is used to boost up a primary charge pump according to a level of an input supply voltage. The intermediate voltage has a higher level than that of the input supply voltage, and is provided to boost up the primary charge pump when the input supply voltage is determined to be lower than a threshold voltage. Such a charge pump based voltage generator is compatible to a wide input supply range, capable of sustaining a large output load and effectively reduces the chip estate.
