plz help

Questions:

* Your schematic has several stages. Did you try a single stage? Did it work?

* Are your mosfets biased to a sufficient volt level so that they turn on? (It needs to be greater than the node at the source pin.)

* Which capacitor accumulates the output voltage? The neighboring mosfet needs to be biased several volts higher.
