Abstract
Method and circuitry for improving noise immunity of differential data channels that use a shared reference channel by substantially matching their respective noise transfer functions. Any combination of various circuit parameters at the reference channel including termination resistance R, channel impedance Zo, and parasitic inductance L are scaled to substantially match the noise transfer function of the reference channel to that of the data channels.
