Paper Abstract

This paper aims at describing a miniaturized CMOS implant- circuit for human medical telemetry. The chip includes a silicon antenna working on the principle of inductive coil coupling through the skin, an rf rectifier for power supply, an hf filter and logic circuitry for chip control. A CMOS compatible temperature sensor is included in the same chip. The obtained measurements are sent back to the coupled antenna and received outside the patient's body. Two prototype chips have been designed in a CMOS 1.0 micrometer technology with encouraging results. The chips include the separate basic blocs of the micro-system: rectifier, integrated or external antenna, analog filters, sensors and logic systems.
