Digging Out The Details On Embedded Capacitance

Capacitance is a part of every circuit design, whether intended or not. Chip capacitors are available in a wide range of sizes for every function from blocking DC to filtering microwave signals. But as small as they are, chip capacitors still occupy valuable area on a printed-circuit board (PCB), and mounting them—even by machine—can be labor intensive and time-consuming. For these and several other reasons, a method for fabricating PCBs with embedded capacitance provides a way to simplify and miniaturize some circuit designs. But is it right for your design?
