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