Abstract

This paper presents an RF front-end of a fully integrated inductively powered implantable circuits for blood flow measurement, which are embedded within vascular prosthetic grafts for early detection of graft degradation or failure. The effect of human body on the helix coil design has been carefully characterized. An equivalent circuit model of the coil has been developed. An adaptive link compensation technique was adopted in the backscattering modulator design. A highly efficient rectifier was designed to achieve 65% efficiency.
