该论文提出了一种915MHz非对称无线电架构，采用Q增强放大器，实现了完全集成的3×3×3mm³无线传感器节点，能够在非视距场景下实现20米通信距离。主要解决了毫米级节点天线效率低和薄膜电池瞬时电流限制（约10μA）的挑战。

The major technical challenges posed by a mm-scale form-factor are poor antenna efficiency and the small instantaneous current limit (~10s of μA) of thin-film batteries. We address these challenges in several ways: 1) We found that a magnetic dipole antenna achieves better efficiency at an electrically-small size than an electric dipole, when the antennas are resonated with off-chip lumped components. In addition, the high impedance of electricallysmall electric dipoles (~4kΩ compared to 10Ω for the magnetic antenna) requires an impractically large off-chip inductor to resonate. 2) By simultaneously
