  • Programmable charge pump device
    Patent number: 6801077
    Abstract: The invention relates to charge pump device and a display driver with a charge pump device. Further it relates to a display module with a display driver using a charge pump device and a telecom terminal having such a display module. To provide a device which needs a charge pump for generating a higher voltage as the supply voltage a charge pump device is proposed containing at least two stages (S), whereby a stage (S) comprises a switch (SWn) and a charge device (CSn) which are arranged to generate a voltage higher than the supply voltage (Vdd), whereby the stages (S) are arranged in serie and a required multiplication factor (MF) of the charge pump (CP) is adjustable by activating/deactivating a definable number of stages (S), whereby the switches (SWn) of each stage (Sn) are arranged in the same way.
