Abstract
Disclosed herein is a charge pump architecture in which boosting capacitors of adjacent stages are connected only by NMOS type transistors and comprising a first stage receiving a first voltage and outputting an internal voltage; a second stage receiving the internal voltage and outputting a second voltage at an output terminal, and an auxiliary stage connected to the output terminal, the first stage and second stage including a first type of MOS transistors transferring the voltage from input node internal boosting nodes and being cross-coupled; a second type of MOS transistors with their gate biased by a third type of MOS transistors and fourth type of MOS transistors; the third type of MOS transistors connecting the gate of the second type of MOS transistors; and the fourth type of MOS transistors connecting the gate of the second type of MOS transistors.
