SWITCHING RIPPLE DATA TRANSFER TECHNIQUE USING STEP-DOWN DC-DC CONVERTER
This paper describes an electronic communication method based on the use of the DC-DC converter as a data transfer device. Output voltage of a DC-DC converter is modulated with Amplitude-Shift Keying (ASK) signal carrier. Modulation takes place in the feedback loop of the DC-DC converter. The output signal passes through the transition line to the band pass filter, where unexpected noise and DC components are removed. Transition line is represented as a long wire with a certain length that contains active and reactive parasitic parameters.
