| Summary: | 碩士 === 國立中正大學 === 資訊工程研究所 === 105 === 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.
