摘要

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以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。
人體通訊(Human Body Communication)是WBAN(Wireless Body Area Network)中的一種通訊方式，把人體當作通道來傳送訊號。無線通訊和醫療的需求增加，IEEE制定了802.15.6此人體通訊標準，與其它IEEE802.15 無線標準相比，該無線通訊技術對人體安全有非常高的要求並且需要好的QoS(Quality of Service)與數據速率與低功耗等。
本論文提出了一種適用於穿戴式裝置的低功耗人體通訊接器電路設計。 該接收器電路架構採用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。所提出之接收器電路在僅有162.3μW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162.3 pJ的最小能耗。

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.
Human Body Communication (HBC) is a communication method in Wireless Body Area Network(WBAN), which uses the human body as a channel to transmit signals. The demand for wireless communication and medical care has increased. The IEEE has established the human body communication standard 802.15.6. Compared with other IEEE802.15 wireless standards, the wireless communication technology has required very high for human safety and good Quality of Service(QoS)、data rate and low power consumption.
An low power human body communication (HBC) receiver applied for wearable devices is presented. The receiver 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 162 μW. Thus, minimum energy consumption per received bit of 162 pJ can be achieved.
