In this article, a body channel communication (BCC) transceiver (TRX) and low-power receiver (RX) that can cover wide applications are proposed. The IEEE 802.15.6 human body communication (HBC) physical layer (PHY) standard and high-speed data transmission are supported simultaneously with a single chip. First, the sinusoidal-modulated transmitter is proposed for the standard mode TRX, and it can reduce filtering power overhead 35%. Second, high-speed TRX is proposed that can support dual-band QPSK modulation to increase system data rate and bandwidth efficiency. Third, on-chip RC duplexer is proposed for full-duplex function in communication. Also, for the low-power RX, a wireless power transfer (WPT)-based wake-up receiver (WuRX) and a higher energy efficiency main RX is integrated into RX chip. The main HBC RX demodulates both ASK and frequency-shift keying (FSK) information with a sharing oscillator (OSC) with 31- $\mu \text{W}$ low-power consumption. The TRX and RX are implemented in 65-nm CMOS process.

具有高应用扩展性的无线体域网收发器和低功耗接收器

在本文中，提出了一种可以覆盖广泛应用的身体信道通信 (BCC) 收发器 (TRX) 和低功耗接收器 (RX)。单芯片同时支持 IEEE 802.15.6 人体通信 (HBC) 物理层 (PHY) 标准和高速数据传输。首先，针对标准模式TRX提出了正弦调制发射机，它可以减少35%的滤波功率开销。其次，提出可以支持双频QPSK调制的高速TRX，以提高系统数据速率和带宽效率。第三，针对通信中的全双工功能提出了片上RC双工器。此外，对于低功耗 RX，基于无线电源传输 (WPT) 的唤醒接收器 (WuRX) 和更高能效的主 RX 集成到 RX 芯片中。主 HBC RX 使用具有 31-$\mu\text{W}$ 低功耗的共享振荡器 (OSC) 对 ASK 和频移键控 (FSK) 信息进行解调。TRX 和 RX 采用 65-nm CMOS 工艺实现。
