A Four-Camera VGA-Resolution Capsule Endoscope System With 80-Mbps Body Channel

Abstract

A small form-factor, lightweight wireless capsule endoscope (WCE) system with body channel communica- tion (BCC) transceiver ICs is proposed for VGA-resolution image transferring and capsule localization. The transceiver ICs are composed of capsule chip and receiver chip, implemented in a 65-nm CMOS process. In the capsule side, the proposed system provides 360° image capturing through four-camera integra- tion to reduce the miss rate. Also, a dual-band pulse-shaping BCC transmitter is proposed
