Hi all, Did somebody have formula or experience in how ferrite rod affect the on-chip inductors ? for example the ferrite permeability is 1000, can inductance increase as much as nearly 1000? and how does resistivity affect the inductance ? -----as I think it affects E-field . Thank you in advance for your helpful recommendation . B est regards, Zhou Lin --------------------------------- Do you Yahoo!? Yahoo!
