Printed Circuit Board Power Bus Decoupling Questions

1. What is the best strategy for connecting decoupling capacitors to a printed circuit board?
2. What is the best method for connecting decoupling capacitors if my PCB does not have a power plane?
3. What is the best method for connecting decoupling capacitors if my PCB has closely spaced power and ground planes?
4. What is the best method for connecting decoupling capacitors if my PCB has power and ground planes, but they are not closely spaced?
5. Should decoupling capacitors be located near the Vcc pins or near the ground pins of an active device?
6. How effective is embedded capacitance for power bus decoupling?
7. How do I estimate the amount of power bus noise on a printed circuit board that hasn't been built yet?
8. Can I use lossy capacitors or resistors to eliminate power bus resonances?
