Abstract
A two-wire medical implant, method and system for transferring power and data over a two-wire connection between a first medical implant and a second medical implant. The second medical implant comprises a clamping circuit for extracting the data. In one form, the second medical implant also comprises a voltage multiplier which is formed in part by the clamping circuit. In one embodiment, the second medical implant also comprises a DC decoupling capacitor which forms a part of the clamping circuit. The medical implant and medical implant system may be used in a cochlear implant system.
