摘要

可穿戴/可植入设备，例如心率监测仪带和植入式无线传感器，需要超低功耗(ULP)，紧凑，并且还能抵抗接近效应，这可能会显著降低天线和前端性能，从而降低电池寿命。采用低功耗和快速阻抗检测的完全集成的自适应前端与可调谐匹配网络(TMN)是非常理想的，以实现鲁棒和高效的操作。

17.4 A sub-mW antenna-impedance detection using electrical balance for single-step on-chip tunable matching in wearable/implantable applications

Wearable/implantable devices, e.g., heart-rate-monitor straps and implanted wireless sensors, need to be ultra-low-power (ULP), compact, and also robust against the proximity effect, which can significantly degrade the antenna and front-end performance and hence battery lifetime. A fully integrated adaptive front-end with a tunable matching network (TMN) using low-power and fast impedance detection is highly desirable for robust and efficient operation.
