Patent ID: 7202710

Claim:
A driver apparatus for handling interdevice signaling between a sending device and a receiving device; the apparatus comprising: (a) a driver core section; said driver core section having at least one input locus for receiving an input signal from said sending device and having at least one output locus for presenting an output signal for said receiving device; each respective said at least one output locus presenting said output signal in response to said input signal received at a respective said input locus of said at least one input locus; (b) a feed forward circuit coupling each said respective input locus with its respective corresponding output locus to provide a feed forward signal to said respective corresponding output locus; said feed forward signal being in phase with said input signal, wherein said feed forward circuit is embodied in a plurality of n feed forward circuit segments coupled in parallel; selected feed forward circuit segments of said n feed forward circuit segments being switchably and separately capacitively connected with at least one of said respective input locus and a corresponding output locus for controlling electrical inclusion in the apparatus.
