摘要
提出了一种用于仿生手臂的电偶体通道通信(GCBCC)收发器(TRX)，该收发器具有鲁棒性通信和人体安全性。GC-BCC减轻了环境变化和干扰的影响。在RX输入端一个简单的终端可以拓宽信道带宽(BW)，实现100Mb/s的通信。可植入TX通过采用电流调节通道驱动器、电荷平衡方案和双极RZ (BRZ)编码产生的双相波形来保证用户的安全。在0.18 mm CMOS中制造的TRX IC实现了10-9的低误码率(BER)， TX和RX的能量效率分别为4.75pJ/b和26.8pJ/b。
A 100Mb/s Galvanically-Coupled Body-Channel-Communication Transceiver with 4.75pJ/b TX and 26.8 pJ/b RX for Bionic Arms
A galvanically-coupled body-channel communication (GCBCC) transceiver (TRX) is proposed for bionic arms, offering robust communication and human-body safety. The GC-BCC mitigates the influence from the environmental changes and disturbances. A simple termination at the RX input widens the channel bandwidth (BW), enabling 100Mb/s communication. The implantable TX guarantees the user’s safety by employing a current-regulating channel driver, a charge-balancing scheme, and a biphasic waveform generated by bipolar RZ (BRZ) encoding. The TRX IC fabricated in 0.18 mm CMOS, achieves a low bit-error rate (BER) of 10-9 with excellent TX and RX energy efficiencies of 4.75pJ/b and 26.8pJ/b, respectively.
