Abstract
Embodiments relate to enhancing echo cancellation in a transceiver integrated circuit (IC) for full-duplex communication by providing a signal path connected to a dummy driver that replicates a signal path between a main driver and a counterpart transceiver IC to cause a duplicated signal generated by the dummy driver to more closely replicate a sending signal generated by the main driver. The signal path connected to the dummy driver includes circuit elements having transmission line parameters and RLC parameters that replicate transmission line parameters and RLC parameters of circuit elements in the signal path between the main driver and the counterpart transceiver IC.
