In one embodiment, a bus coupled includes a voltage control circuit configured to selectively conduct a current from the first current source away from an output of the coupler to regulate a voltage drop across the another current source to a first value. An embodiment of a method of forming a bus coupler may include configuring a circuit to store energy from the input into a first storage element in response to receiving an active portion of an input signal, and to transfer energy from the storage element to the output after termination of the active portion of the input signal.
