Abstract
A circuit board has an edge connector with signal traces. The signal traces are formed on a dielectric layer of the circuit board. A reference trace is formed within the dielectric layer or on another surface of the dielectric layer. Parameters of the reference trace are adjusted to set an impedance of a single-ended signal trace or a differential impedance of two adjacent signal traces.
