Ulm, Germany, 3Intelligent Medical Implants, Bonn, Germany Improving communication with implantable systems remains an important topic of research due to the limitations in power dissipation and the simultaneous need for high data rates. Neural recorders generate well above 10Mb/s data [1], which needs to be transmitted out-of-body. Multichannel stimulators, such as epiretinal implants, need control data in the range of several Mb/s for the intobody link [2]. Up to now, RF has been the dominant form of transcutaneous communication. One major issue is the crosstalk between the RF power link and the data signal. Therefore, dual-band telemetry is common in order to spectrally separate the data and power transfer. The standards reach from UWB transmitters [1], MICS band [3], to customized [2] RF receivers, often using sophis
