    摘要: A ground layer of a printed circuit board (PCB) includes a digital area, an analog area, and a connecting portion. The digital area is connected to the analog area via the connecting portion. The connecting portion with one end connected to the digital area, and the other end connected to the analog area follows a path resembling a labyrinth. The connecting portion replaces a conventional linear connecting portion and a plurality of chip capacitors. The connecting portion improves noise filtering effect and reduces cost as well.
