• We investigated the problem of constructing a near-field link budget to wirelessly communicate with high data rate (e.g. 3.125 Mbps) implantable circuitry located few centimeters under the skin using spread spectrum technique. Different methods and frequency bands were analyzed to choose the appropriate 2.4-GHz ISM band. The nominal power consumption of the implantable baseband communications circuitry was estimated for smaller technology nodes using the Synopsys CAD tools. The effect of using the ultra low power subthreshold operation in different technology nodes was also analyzed using predictive technology models. By introducing an analysis flow and the corresponding implementation code, we were also able to predict the subthreshold power consumption of the circuitry in different technology nodes and importantly at the gate level.
