  • Electronic component with reduced inductive coupling
    Patent number: 6693785
    Abstract: The invention relates to an electronic component comprising a package PACK including input pins PIi and output pins PSj, and an integrated circuit IC, encased in the package PACK, which integrated circuit is provided with input contact pads CIi and output contact pads CIj, which are connected, respectively, to the input pins PIi and the output pins PSj of the package PACK by conducting wires WIi and WSj. In accordance with the invention, each current path connecting an input contact pad CIi to an output contact pad CIj comprises a buffer element Bi having a high input impedance. Said high input impedance of the buffers substantially reduces the value of the current Ii flowing through the conducting wires WIi connecting the input pins PIi to the input contact pads CIi, and hence the inductive coupling between said conducting wires.
