In telecommunication, an artificial transmission line is a two-port electrical network that has the characteristic impedance, transmission time delay, phase shift, or other parameter(s) of a real transmission line. It can be used to simulate a real transmission line in one or more of these respects.

Hybrid distributed driver
ActiveUS12652012B2Amplifiers wit coupling networksDifferential amplifiersArtificial transmission lineSoftware engineering
A distributed driver for an optic signal generator comprising amplifier cells having an amplifier cell input configured to receive the input signal and amplifiers configured to amplify the received signal to create an amplified signal, and an amplifier cell output. The distributed driver also includes an input path connected to the amplifier cell input to receive the input signal and distribute the input signal to the two or more amplifier cells. The input path includes one or more buffers configured to introduce a delay into the input signal. An output path is provided and connects to the amplifier cell outputs of the two or more amplifier cells. The output path is configured to receive the amplified signal and the output path includes one or more inductors that incorporated with the parasitic capacitance from the two or more amplifier cells form the LC segments of an artificial transmission line.
