Abstract

One of the areas where the technological developments in biomedical applications can be used most effectively is the neurological monitoring systems. Wireless data communication systems enable complete implantation of monitoring circuits for intracranial recordings. This chapter explains how bidirectional wireless data communication is established for the implanted neural monitoring system. A downlink communication using low power pulse position modulation is investigated to program the remotely powered implant. Two alternative methods, namely narrowband and ultra-wideband transmitters, are designed to perform transmitting the amplified, quantized, and analyzed neural activities to the external unit. The presented circuits are fabricated, and their characterizations are validated with measurement results.
