Abstract


In this paper, we have presented a new custom smart CMOS image sensor (CIS) for low power wireless capsule endoscopy. The proposed new smart CIS includes a 256 × 256 current mode pixels array with a new on-chip adaptive neuro-fuzzy inference system that has been used to diagnosing bleeding images. We use a new pinned photodiode to realize the current mode of active pixels in the standard CMOS process. The proposed chip has been implemented in 0.18 Micro m CMOS 1P6M TSMC RF technology with a die area of 7 mm × 8 mm. A built-in smart bleeding detection system on CIS leads to decrease in the RF transmitter power consumption near zero. The average power dissipation of the proposed smart CIS is 610 Micro W.
