  • Signal trace phase delay
    Patent number: 6738919
    Abstract: A technique for reducing electromagnetic interference (EMI) in electronic systems that provides a phase shift between signals having a common frequency component propagating on adjacent portions of circuit board signal traces. The phase shift is produced by a delay element in one of the adjacent signal traces. In one example, the delay element includes a serpentine delay located at the signal generating circuit side of the adjacent portion of the signal trace. Such a technique can be used to reduce EMI emissions from clock signals provided to RAM circuits of a system memory of a computer system.
