    Hi people,

    I am layout a board. I do not know how get a good layout board. I know
    that the layout process plays a important role for reducing noise. I
    need a board with the minimum noise. I read some document on the
    internet, i separate the digital area and high current area. i try to
    tied all ground together. I hope it will decrease the noise. Can any
    body know more ways to reduces noise when layout?

    Please tell me, if you know
    Best regards,

    Him Lam

  4. Linear Technology (www.linear.com) has several good App notes.

    One is AN25, Switching Regulators for Poets, which briefly touches on
    layout but explains some things about transient currents. Written by Jim
    Williams in 1987, so a bit dated but still applicable.

    The "Big Kahouna" is AN47, High Speed Amplifier Techniques, also by JW in
    1991. It goes deeply into the black magic of high speed design, and has
    good pointers on how to make measurements properly so you see what is
    actually there.

    I would also recommend almost all of Bob Pease's articles
    (www.national.com), Bonnie Baker (originally with www.microchip.com but I
    think now at www.ti.com).
