Abstract
Methods and apparatus are provided for implementing a receiver capable of receiving signals in simultaneous bi-directional current mode differential links. The receiver comprises a resistor-summing network and a differential amplifier. The resistor-summing network can also comprise capacitors for the purpose of attenuating high-frequency noise at the differential amplifier. The high-frequency noise can arise from impedance discontinuities in the signal paths or from differences in rising or falling transition times between the data driver and the replica driver in the links.
