As part of a transmitter and receiver system a droop compensator is provided between the channel isolation device and the driver system to compensate for reduced transition densities. The droop compensator is configured to improve power transfer to the channel in response to reductions in transition density without affecting power transfer during periods of high transition density. The droop compensator creates an impedance mismatch between the matching circuit and driver in relation to the line impedance. The droop compensator may comprise passive elements, such as capacitors, inductors, or resistor, or active elements including transistors or power control modules. The droop compensator may be configured to operate with transformer line couplers or capacitor line couplers, and either current drivers or voltage drivers.
