Looking for materials about the bonding wires inductor

bonding wire

Can anybody give me some material about the bonding wire's inductor?
How the inductor of bonding wire influnce a outputed high speed analog signal? How the inductor of bonding wire influnce the voltage of power & gnd?

Re: bonding wire

You may get the material from the package.
In simple view, you may get some idea from the formula
V= L(di/dt)
L is the inductor of bond wire.
di/dt is the signal related with your speed.
So if you have a high speed toggle signal or large bond wire inductor
Your signal will have a large overshoot/undershoot.
And Power and Ground also will have bouncing noise, etc.
For more detailed information, you may try to see other books.

bonding wire

You can look for some chip vendor's IBIS model .
It include the package inductance and resistance .
For IBIS info , you can take a look at https://www.eigroup.org/ibis/ckbook1.htm

Re: bonding wire

it is all about "simultaneous switching output"
here is a good paper

Re: bonding wire

The bond wire inductance vaires from few nH to tens of nH. Basically it depends upon the type of package you are using. (also the type & dimension of the Bond wire). Normally Gold is used as bond wire.

This bond inductance results in over shoots/ undershoots. & Becomes a chalenge for those who are working for high speed circuits.
