Abstract
A method for achieving a desired value of electrical impedance between conductors of an electrical power distribution structure by electrically coupling multiple bypass capacitors and corresponding electrical resistance elements in series between the conductors. The resistance elements may be annular resistors, and may provide the designer a greater degree of control of the system ESR. The annular resistors may comprise a first terminal, an annular resistor, and a second terminal. The second terminal may be located within the confines of the annular resistor. The annular resistors may be printed onto a conductive plane (e.g. a power plane or a ground plane), or may be a discrete component.
