Voltage Doubler using cmos(analog integrated circuits)

I need to design a voltage doubler using cmos. Input voltage being 3.3 volts and output must be greater or equal to 6 v.

Output resistance=100kohms
output resistance=1uF
180 nm cmos technology
max efficiency
and
low layout area

I want to use opamp for this topic but i am unable to find any circuit related to it.
any help will be appreciated.

Hi,

Don't know about that, I don't recollect op amp versions. In my ignorance, at its simplest, the diode and capacitor version isn't workable in CMOS? Or why not consider copying the concept behind the flying capacitor one with four switches.

Maybe you can make use of something in the rar file, it's an assortment of charge pump related pdfs, some of them/a few are specifically about CMOS charge pumps.

Hope anything in there is useful for you.
