3 micro amperes charge pump topology needed

[Ahmed Abd El Wahab]

Hello,
I need to design a three branches charge pump with total current of 10-uA. roughly each branch with 3.3-uA. I searched many low/Ultra low power CP architectrues, but didn't find any thing that low. I'm working on TSMC13RF technology. Do u know any design/Arch that may help ?!

Thnx in advance

Hi Ahmed
Are you looking for PLL charge pump?

Yes I'm looking for a low power CP topology for a low power PLL used for a Low power RF Bluetooth receiver.
