This is directed to self-shielded components and methods for making the same. A self-shielded component can include an electromagnetic interference (EMI) shield that contains circuitry within a shielded space defined by the EMI shield. Self-shielding can be achieved by interfacing a conformal shield layer to a ground layer disposed on or within a substrate of the self-shielded component. The combination of the conformal shield layer and the around layer can form a boundary of the shielded space that envelops circuitry requiring shielding. This enables the self-shielded component to be mounted to a circuit board without requiring a shield can or other processing to impart EMI shielding. In addition, the self-shielded components include the benefits of EMI shielding while simultaneously decreasing space requirements.

An electronic device may contain clock circuits, transmitters, and other circuits that serve as sources of noise signals. The noise signals may be characterized by a noise spectrum. The noise spectrum produced by a noise source can be adjusted by adjusting spread spectrum clock circuitry in a clock circuit, by adjusting data scrambling circuitry in a transmitter circuit, or by making other dynamic adjustments to the circuitry of the electronic device. During operation of the electronic device, sensitive circuitry in the device such as wireless receiver circuitry may be adversely affected by the presence of noise from a noise source in the device. Based on information such as which receiver bands and/or channels are being actively received and target sensitivity levels for the receiver circuitry, control circuitry within the electronic device can determine in real time how to minimize interference between the noise source and the wireless receiver circuitry.
