Driver circuit for a two-wire conductor and method for generating two output currents for a two-wire conductor

A driver circuit for a two-wire conductor, the driver circuit comprising:

• a first output stage that generates at an output a first output current from a two-state logic input signal, the first output stage being adjustable as to a magnitude of the first output current;
• a second output stage that generates at an output a second output current from the input signal, the second output current being complementary to the first output current;
• and
• a controller coupled to the first and second output stages for analyzing output voltages appearing at the outputs of the first and second output stages, deriving an error signal from the output voltages within each of at least two time slots subsequent to a change in state of the input signal, caching the error signal or a signal derived therefrom and adjusting, as a function of the cached signal, the first output current of the first output stage in arbitrary time slots subsequent to a proximate change in state of the input signal.
