Wireless Telemetry for Electronic Pill Technology
[attachment=16550]

INTRODUCTION
Recent development in electronic pill technology requires
the integration of more complex systems on the same platform
when compared to conventional implantable systems.


IW-UWB TELEMETRY FOR ELECTRONIC PILL
Several transmitters have been designed to generate UWB
Although the image based electronic pill systems listed in signals. Short pulses are mainly generated according to the
Table I & II can provide some level of accuracy, for some OOK and Pulse Position Modulation (PPM) modulated signal.
diseases detailed images may be required [21]. Thus a better At the transmitter, the pulse generator unit produces a
