Abstract:
A method and apparatus is provided for use in an integrated circuit or printed circuit board for reducing or minimizing interference. An inductance is formed using two or more inductors coupled together and configured such that current flows through the inductors in different directions, thus at least partially canceling magnetic fields. When designing a circuit, the configuration of the inductors, as well as the relative positions of portions of the circuit, can be tweaked to provide optimal interference or noise control.
