Abstract
A driver circuit and method for generating two complementary output currents from a two-state logic input signal at two outputs for connecting a two-wire conductor provide the following actions: generating from the input signal, an output signal at each output, the amperage of one of the output currents being adjustable by a control signal; analyzing each voltage materializing at the outputs; generating an error signal as a function of the output voltages within each of at least two time slots subsequent to a change in state of the input signal; caching the error signals or signals derived therefrom and adjusting, as a function of cached error signals or of the cached signals as a function thereof, the output current in corresponding time slots subsequent to a resulting change in state of the input signal.
