Hi everyone,
I have a kinetic energy harvesting device which, when moved around produces a varying voltage amplitude in the order of 200mV and current in the order of nanoamps.
I would like to convert this into useful energy (i.e. a DC voltage) and therefore have looked into building a synchronous rectifier with the use of schottky diodes, mosfets and op-amp comparators. I have attached the schematic of what I want to do.
The problem I am having is, I'm not sure if it is possible to get such low ratings on the components, do I need some kind of boost converter first? I would like to build it on a breadboard / verroboard and people I have seen who have done this are fabricating it on silicon which obviously I am no able to do. Any help would be much appreciated.
Cheers
