Developing Innovation - Wireless Transceiver Design for Implantable Medical Devices

In recent years, demands on electronic implantable medical devices (IMDs) are significantly increasing. It is quite challenging to design energy-efficient IMDs. IMDs requiring wireless connection have two types of communications, i.e., the sensor data transmission, and the command/control information exchange. The design considerations for wireless IMD transceiver is reviewed, and a dual-band/mode transceiver architecture with high energy efficiency is proposed for the IMDs. The integrated circuit implementation techniques have been investigated. This is an ultra-low power transceiver working in the 400MHz frequency band and the 2.4GHz band simultaneously with a shared antenna.
