Abstract
An Ethernet or other communications module can amplify and reinforce a signal received from a non-local source without requiring a transformer or other magnetic component. A semiconductor integrated difference amplifier circuit can be used to amplify and reinforce a differential mode component of the received signal, while also attenuating a common mode component of the received signal. A transmission compensation network can generate a phase-shifted version of a locally transmitted signal being placed on the same communication terminals as the received signal during full duplex communications, for cancellation of such locally transmitted signal at inputs of a local receiver circuit. This can enhance detection of the received signal generated by the non-local source.
