title: A Fast Passive Data Transmission Method for ENG Telemetry.
abstract: The objective of this study was to develop a high bit-rate passive method for conveying ENG signals from implants which would work over a wide range of coupling coefficients. A novel method, Passive Phase Shift Modulation, was studied in theory, by simulation, and implemented in the laboratory. A binary signal of 222 kbit/s was passed on a 4-MHz carrier (ratio 1:18) with coil-coil spacings up to 70 mm (coil diameters are 45 and 60 mm) with an addition to the power consumption equivalent to 2 mW in the implant. We conclude that this is a satisfactory method to be used as part an implant for conditional neuromodulation that we are designing.
