A simple, highly efficient class-E driver circuit suitable for powering implantable electronic devices is described. Such a driver allows the design of displacement-tolerant coils. The design for a driver operating at 120 kHz is given. Through successive adjustments in frequency and duty cycle the largest current transfer ratio of peak AC current in the transmitter coil (L2) to the input DC current was obtained. The frequency of operation was 122.7 kHz with a duty cycle of 0.18. The DC input…
