Design and Fabrication of 1.2GHz range RF Transmitter and Receiver for Bi-directional Capsule Endoscopes
양방향 캡슐형 내시경용 1.2GHz 대역 RF 송수신기 설계 및 제작
Abstract
The Bi-directional Wireless Capsule endoscope con sists of CMOS Image sensor, FPGA, LED, Battery, DC to DC Converter, Transmitter, Receiver and Antennas. The RF transmitter at 1.2GHz range is designed and fabricated with 10 mm(diameter)x1.6 mm(thickness) dimension considering the maximum permission exposure(MPE), system size, power consumption, linearity and modulation method. The fabricated RF receiver at 400MHz range can demodulate the external signals so as to control the behavior of CMOS image sensor. four LEDs and Transmitter.
