Need papers on charge pump Voltage doubler design using CMOS

[suhas_shiv]

voltage doubler in spanish

Can somebody give me papers/reports on design of High Current(>50mA) charge pump Voltage doublers using CMOS? I have tried looking on the web but all I can find is PLL charge pumps which use very little current. I need one for very large current?
Thanks

Voltage Doubler

what is your target voltage?

you may need a bigger flying capacitor, higher clocking frequency, and more stages to achieve such a high load.

Target voltage is 6V. Yeah, i might have to use a very big cap to achieve this. Still unsure about the exact operating frequency. Would appreciate if someone can provide me design papers/report on something like this.

Thanks,
