A passive equalizer circuit is embedded within a substrate of a package containing an integrated circuit. It is believed that substantial reduction in uneven frequency dependent loss may be achieved for interconnects interconnecting the integrated circuit with other integrated circuits on a printed circuit board. Other aspects are described and claimed.

Package embedded equalizer

A circuit board may include first and second sides, a plurality of circuit board layers between the sides, and a plurality of signal traces located in respective circuit board layers. The circuit board layers and the signal traces may extend from a first component connection region at the first side of the circuit board to a second component connection region at the first side of the circuit board. The signal traces may thus form stubless signal paths through the circuit board between the component connection regions. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
