Abstract
A multi-layered substrate has a voltage reference signal circuit layout therein. A major change in the design of the multi-layered substrate is the moving of a reference signal trace from a signal layer to a non-signaling layer. Once the reference signal trace is moved, the signal traces within the signal layer can have a larger layout area. Similarly, the reference signal trace within the non-signaling layer can have greater layout flexibility in addition to electromagnetic shielding from other signal traces. Moreover, the reference signal trace having a greater width may be used to reduce parasitic resistance within the reference signal circuit.
