Patent ID: 7550853

Claim:
A monolithic electronic chip comprising: a substrate including: first and second opposing surfaces; a first circuit having a first end disposed on at least one of the first or second opposing surfaces; a second circuit having a second end disposed on at least one of the first or second opposing surfaces; and at least two through-holes extending from the first surface to the second surface and positioned between the first and second ends; the at least two through-holes positioned so that the through-holes do not touch the first, second, or any other circuit; at least two conductive impedance taps, each conductive impedance tap formed within one of the at least two through-holes in the substrate and electrically coupled to a reference voltage; wherein: a first impedance value between the first circuit and the at least two conductive impedance taps via the substrate is less than a first-second crosstalk impedance value between the first circuit and the second circuit via the substrate; a second impedance value between the second circuit and the at least two conductive impedance taps via the substrate is less than the first-second crosstalk impedance value, and the first and second circuits are disposed in a monolithic semiconductor chip.
