A pseudo-differential signaling system uses a plurality of signal lines
and a single, common reference voltage. Signal line voltages are
interpreted only in comparison to the reference line voltage. Within a
receiving circuit, the reference line is buffered prior to its
distribution to multiple comparators. The system utilizes an active
buffer having a bandwidth that is significantly greater than the resonant
input frequency of the receiving circuit. In an alternative embodiment,
the signal lines are also buffered. In this embodiment, the buffers are
implemented with transistor-based source-followers. The buffer associated
with the reference line has a larger current capacity than the buffers
associated with the signal lines. In yet another embodiment, a comparator
produces a correction signal that is equal to the noise present on the
signal lines. This noise is then subtracted from the signal voltages.
