Abstract
A ground assembly includes a first layer, a second layer, and a bypass capacitor. The first layer includes a power ground, a communication ground spaced from the power ground, a conductive path defining a parasitic inductance and electrically coupled between the power ground and the communication ground, and an electrically insulating layer. At least a portion of the insulating layer is positioned between the power and communication grounds. The second layer includes a first substrate that is spaced from the power ground to define a first parasitic capacitance therebetween and is spaced from the communication ground to define a second parasitic capacitance therebetween. The bypass capacitor is electrically coupled between the power ground and the first substrate.
