Electronics manufacturers are squeezing greater functionality into smaller, more portable products, and the number of passive devices required for these products has increased significantly. For example, the typical Pentium III motherboard uses approximately 2,200 passive devices. As another example, 500 of the 550 devices on the printed circuit board (PCB) of a typical cell phone are passives. The growing number and types of passives used in PC motherboards are listed in Table 1.
Designers have several choices for accomplishing the passive functions: discrete passives, array passives, passive networks, integrated passive devices and embedded passives. Table 2 ...
