10.07uW Multi-Mode Baseband Transceiver for Encrypted Capsule Endoscopy

This paper proposes an ultra-low-power multi-mode baseband transceiver for capsule endoscopy. We set a new specification for capsule endoscopy to achieve ultra-low power and short-latency transceiver. The proposed baseband transceiver can operate multi-mode to transmit ten images per seconds depending on the presence of the lesion and the position of the capsule endoscope. The proposed one does not require memory and optimized all the logic and architecture levels. The proposed BCH decoder uses the early termination scheme to reduce the 51.16% of latency and 45.78% of power consumption, respectively. In addition, the advanced encryption standard (AES) processor protects the biomedical information. As a result, we implemented the proposed multi-mode baseband in Verilog-HDL and synthesized by using the Samsung 65  nm CMOS standard cell library. The proposed baseband shows 10.07 μ W (0.9 V, @10 MHz) of total power consumption .
