Topology of CMOS DC-DC converter for Piezoelectric MEMS

Hello Guys,

What type of DC-DC converter CMOS topology is normally used for applications that harvest energy from Piezoelectric MEMS?

Thanks!

I'm not sure there is such a thing as "normal" for either
MEMS or energy harvesting therefrom. You maybe ought
to start with "power take" assessment of the piezo MEMS
element - which will surely have bounds of tolerable force /
pressure, hence voltage, and likely source-limited in current
(cycle frequency).

Similarly your load expectations, through reasonable DC-DC
efficiency and input-range limits, need to be back-checked
against what's possible to receive, raw and forward-checked
against candidate DC-DC topologies and conversion ratios.

If you want a spoonful of paper digests, I've got nothing
for you but bet the InterWebz has much if you ask the
right questions (or read what comes up just for piezo MEMS
energy harvesting). People trying to sell such schemes are
going to leave a pretty good e-snail-trail.
