Abstract

This paper presents a novel analog-digital mix-mode low power IC implemented in a CMOS process used for a bi-directional digital wireless endoscope capsule. The proposed system can implement the diagnoses of whole human digestive tract. It has some characterized features such as real time endoscopy image monitoring, adjustment of the view angle and focus, 3-dimension range image acquisition, and controllability of capsule movement. The architecture, specifications and characteristics of the IC are demonstrated.
