摘要

論文提要內容：
隨著生醫電子應用的快速發展，將晶片穿戴或植入人體用以偵測各種生理訊號或是進行藥物釋放成達到居家照護的目的將成為趨勢。由於此類晶片的電源來源為電池、體熱發電或是無線電能量收集電路，因此在其傳輸介面電路設計上最重要的要求為超低功率消耗，以達到延長使用壽命的目的。由於接收器必須長時間維持開啟狀態，因此接收器的功率消耗佔了整體功率消耗的一半以上，因此實現一超低功耗接收器可大幅延長使用時間。
本論文提出了一種適用於穿戴式裝置的低功耗人體通訊收發器。 該收發器採用UMC 0.18 µm CMOS製程。應用於穿戴式裝置時，高功率效率可使穿戴式裝置的使用時間大大提高。所提出的接收器在僅1.79 mW的功耗下實現了1 Mb / s的最大傳輸速率。因此，可以實現每接收位1.79 nJ的最小能耗。發射器在10 Mb / s的最大發射傳輸速率下消耗700μW。 因此，每個傳輸位元的最低能耗為70 pJ / bit。

As age advances, the electronic applications in the biomedical develops rapidly. It is the trend that people carry chips or implant chips into their body in order to detect a variety of physiological signals. Also, they use chips to release medicines to achieve the purpose of home care. As those chip’s power source used for the battery, the power generation of body heat or radio energy harvested circuit, therefore the most important requirements in transmission interface circuit design for ultra-low power consumption to extend the service life of purpose. Since the receiver must remain turn on for a long time, the receiver's power consumption accounted for more than half of the overall power consumption, therefore to achieve an ultra-low power receiver can significantly extend the used time.
An low power human body communication (HBC) transceiver applied for wearable devices is presented. The transceiver is implemented in UMC 0.18 µm CMOS process. As applying for wearable devices, the high power efficiency leads to a great improvement of lift time of the wearable devices. The proposed receiver achieves a maximum data rate of 1 Mb/s under a power consumption of only 1.79 mW. Thus, minimum energy consumption per received bit of 1.79 nJ can be achieved. The proposed transmitter consumes 700 μW at the maximum transmitted data rate of 10 Mb/s. Therefore, minimum energy consumption per transmitted bit of 70 pJ/bit can be achieved.
