Abstract

In this paper, we present a wireless RF-powering electronics approach in an implantable biomedical microsystem with versatile sensors/actuators toward nanomedicine diagnosis and therapy applications. Miniaturized spiral coils as a wireless power module with low-dropout (LDO) linear regulator circuit convert RF signal into DC voltage provide a batteryless implantation for truly free-behavior monitoring. Presented design achieves low quiescent-current and line/load regulation, high antenna/current efficiency with thermal protection to avoid damage to the implanted tissue. Related characterization demonstrates the proposed design to be applied to the desired nanomedicine microsystem.
