Proposal of the Application-Specific Integrated Circuit and Radio Transceiver Choice for the Wireless Endoscopic Capsule

This paper overviews advantages and disadvantages of CMOS and CCD matrixes used in endoscopic capsules, specifies requirements that should be met by the microcontroller of the device for the improvement of its effectiveness and concludes on the need of developing the application-specific integrated circuit (ASIC) for the wireless endoscopic capsule. The ASIC microcontroller designed especially for the wireless capsule endoscope will improve the specifications of the device in terms of the recorded images` size and the size of transmitted data as well as reduce the energy consumption. The article also deals with radio transceiver choice as it is essential in terms of energy consumption reduction and the data transmission speed increase. The main ISM protocols are compared, namely NRF, Chipcon, Wi-Fi and Bluetooth. The article also provides the power estimation of the proposed ASIC.
