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.
 

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.
