This paper reports a low power transceiver designed for wearable medical healthcare system. Based on a novel energy-efficient wideband wireless communication scheme that uses human body as a transmission medium, the transceiver can achieve a maximum 15 Mbps data rate with total receiver sensitivity of -30 dBm. The chip measures only 0.56 mm(2) and was fabricated in the SMIC 0.18um 1P6M RF CMOS process. The RX consumes 5mW and TX dissipates 1mW with delivering power up to 10uW, which is suitable for the body area network short range application. Real-time medical information collecting through the human body is fully simulated. Architecture of the chip together with the detail characterizes from its wireless analog front-end are presented.
本文报道了一种为可穿戴医疗保健系统设计的低功耗收发器。基于一种将人体用作传输介质的新型节能宽带无线通信方案，该收发器可实现最高15 Mbps的数据速率，总接收器灵敏度为-30 dBm。该芯片尺寸仅为0.56平方毫米，采用中芯国际0.18um 1P6M射频CMOS工艺制造。接收器功耗为5mW，发射器功耗为1mW，发射功率高达10uW，适用于人体区域网络短距离应用。通过人体进行实时医疗信息采集得到了充分模拟。文中介绍了芯片架构及其无线模拟前端的详细特性。
