    Abstract: 隨著科技進步,穿戴式的裝置與個人醫療照護的裝置蓬勃發展。在傳統上,許多醫療的設備,如心電圖、肌電圖皆使用電線來傳遞訊號,對病人來說造成許多不方便,因此無線的人體區域網路開始發展,目前的無線人體區域網路技術透過空氣來傳遞訊號如藍芽、ZigBee,然而都有功率過高以及傳輸速率慢的缺點,因此人體通道傳輸的技術被用於解決這些問題,人體通道傳輸使用人體當成傳輸媒介。人體通道傳輸具有較低的訊號衰減且不容易遭受周遭環境的干擾,此外,人體通道傳輸能達到較高的傳輸速率。 本論文介紹一個寬帶訊號傳收器。在傳送端,資料會使用 NRZI 編碼與位元填充增加資料的變化,且使用封包式傳輸。在接收端,我們採用無參考時脈的資料與回復電路設計,因此可以降低功率的消耗以及減少電路的複雜度,且我們利用多相位來量化相位誤差的方法能夠增加資料與回復電路追蹤能力以及快速的補償相位誤差。此外,在不同的製程、溫度、電壓的變異下,我們所提出的自動校正相位追蹤量方法,能夠計算出補償碼並提供給全數位資料與回復電路控制器,保證在不同的環境變異下,動態地進行控制碼調整增益的補償。
    As technology advances, the wearable personal entertainments and personal healthcare devices are booming. Traditionally, the medical healthcare devices such as electromyography (EMG) and electrocardiography (ECG) use the wireline to transfer the physiological signals, it leads to inconvenient for patients. Therefore, the wireless communication techniques are used to solve this problem. The common type of wireless body area network (WBAN) realization transmits data through the air, such as Bluetooth and ZigBee. However, they have relatively high power consumption and relatively low data rate. Therefore, the body channel communication (BCC) is proposed to solve this problem. The wireless communication transmits the data through the air, but the BCC uses the human body as the communication channel to transmit the data. Moreover, the BCC has relatively low signal attenuation and relatively few interferences in the nearby environment. Furthermore, the BCC can achieve a high data rate. In this thesis, a wideband signaling (WBS) transceiver is proposed. In transmitter part, the data are modulated by a non-return to zero inverted (NRZI) encoder with a bit stuffer. The data are transmitted in the packet format. In the receiver part, the proposed reference-less clock and data recovery circuit (CDR) can reduce the power consumption and circuit complexity. Moreover, the proposed phase error calculation method uses the multi-phase signals to quantize the phase error. The proposed method can enhance the CDR phase tracking ability and compensate for phase error quickly. The proposed automatically phase track gain calibration method can calculate the gain value for the all-digital CDR (ADCDR) controller. In different process, voltage and temperature (PVT) variations, the gain value will be automatically calibrated.
