Hello all,
I am looking for some easy ways to estimate package resonances for
leadframe packages. Since there are no power-ground planes in (most)
leadframe packages, are there any quick rules that can be used? How
would one go about determining the "most potential problem" part of the
package? If the leads and bond wires are short, then could a lumped LC
analysis be used for resonance calculations? With multiple power-ground
leads supplying fast-switching core currents, is is possible to write
down simple calculations for a few GHz application on a small quad
package?
Thanks in advance!
