An efficient wireless power link for high voltage retinal implant
The design and analysis of a power telemetry system with multiple output voltages is presented in this paper. The system includes a Class E power transmitter, cascaded resonant tank, diode rectifiers, reverse data telemetry and regulators. The power loss associated with voltage conversion is minimized by using a proposed cascaded resonant tank. Reverse telemetry senses the power level fluctuation due to the coil movement and reliably provides minimally required power for the implant. The power telemetry system provides 5 voltage levels (tunable up to plusmn 12 Vplusmn2.5 V and ground), each supported by a dedicated integrated regulator except the ground. The maximum deliverable power is in excess of 100 mW when power coils are separated by 1 cm.
