i try to have dc voltage from 0.4 ac voltage using passive ac-dc doubler
but i d'ont know how connect the gate
normally to have a diode connect mosfet i connect the drain to gate
but when i connect the gate to source it give me more output
it is ok to connect the gate to source !!!!
if i connect the gate to source of mosfet (bsh203)
the mosfet work
but normally if Vgs <0 THAN THE MOSFET WORK !!!!!
IT NORMAL TO connect the gate to source in pmos!!!!
thanks
hello
if i connect the gate to drain in pmos mosfet
current goes from drain to source or from source to drain !!!!!!
because when i simulate sometimes it depent on the type of pmos
note : i need to pmos to have passive voltage doubler
thanks
this circuit is a self powred rectifiying electronics for low voltage electromagnetic harvester
and it is combined with piezo source and TE source to have hybrid system to have DC voltage
my input source for Electromagnetic is 0.4v peak to peak with frequency is 35h and input resistance for...
i tyy to simulate in lt spice ac/dc voltage doubler for electromagnetic harvesting
and i use 2 comparators to control 2 pmos
and those comparators used supply voltage vss and vdd (not external power but self powred from the same source electromagnetic)
the probleme is the 2 sources are...
