Tijdschriftbijdrage - Tijdschriftartikel Conferentiebijdrage

© 2015 Published by Elsevier Ltd. A compact wireless power and communication development system for implantable devices was designed and tested with two receiver circuits based on a 433MHz separate RF link and near-field communication link using the power transfer field. Operating ranges were 9 and 6cm respectively. The power transmitter was designed around a Royer oscillator with the possibility of power control and frequency control using a unique Schottky varactor method allowing 560kHz frequency shift.
