WebNov 4, 2024 · Critical length depends on the allowed impedance deviation between the line and its target impedance. Critical length is longer when the impedance deviation is larger. If the line impedance is closer to the target impedance, then the critical length will be longer. If you use the 1/4 rise time/wavelength limit, then you are just guessing at the ... WebDec 30, 2024 · The normal way to provide a low impedance return path between any return current in the power layer and the ground plane is to place a decoupling/bypass capacitor between the power/ground planes. In the above example, the preferable low-impedance path for any return current induced in the power plane is directly into ground on L2, not on L5.
