I have to calculate gate cap, now I got two methods, one is by looking at Vgs vs Qg graph & directly calculate Cgate = Qg/Vgs.
Second is finding separately Cgs & cgD & then adding them.
Problem is both gives two different results.
Plz suggest me some links or application notes where I can calculate these parameters from mosfet datasheet.
