1. A digital to analog converter circuit comprising:
- a controller configured to receive a digital input data stream;
a plurality of wave propagation media wherein some or all wave propagation media are electromagnetically coupled to each other;
one or more electric power source wherein the power from the one or more electric power sources is used to generate electromagnetic pulses; and
an output terminal wherein the output terminal is coupled to at least one of the wave propagation media;
wherein the controller controls the generation and flow of electromagnetic pulses in the plurality of wave propagation media to form a signal at the output terminal which corresponds to the digital input signal.

Abstract
Converter circuits and methods herein describe mechanisms for converting a digital input signal to an analog output signal using a series of transmission lines. The circuits and methods described herein convert to analog signal using very little power, due to inter-coupling of wave propagation media.

13. A method for converting a digital signal to an analog signal, the method comprising:
-
generating a first set electromagnetic waves in a first set of one or more electromagnetic wave propagation media; coupling the first set electromagnetic waves onto to a second set of one or more electromagnetic wave propagation media to generate a second set of electromagnetic waves; combining the second set of electromagnetic waves to form an output signal; wherein the generation of the first set of electromagnetic waves and or the coupling from the first set of one or more electromagnetic wave propagation media onto the second set of one or more electromagnetic wave propagation media is controlled by a controller in response to a digital input data stream. - View Dependent Claims (14, 15, 16)
