Abstract
A low-power half-duplex data link transmits data
at up to 4 Mb/s over coupled inductors across distances of
up to 5 cm. The inductors are part of two resonators which
tune a free-running oscillator to one of their natural modes.
This gives robustness to changes in coil distance and relative
orientation. With load-shift keying (LSK) employed in the remote
transponder, the link is modeled analytically to reveal some
unexpected properties. A complete design guide aids selection
of coil size for ran
