该论文提出了一种针对蓝牙低功耗（BLE）应用的超低功耗射频收发器，在保持低功耗的同时实现了+8dBm的发射输出功率和-58dBc的发射二阶谐波失真（TX HD2）。通过自动校准的集成射频带通滤波器，解决了传统BLE收发器因牺牲RF性能导致覆盖范围小、抗干扰能力差的问题。
Internet-of-Things (IoT) applications, highly integrated ultra-low-power (ULP) RF transceivers are essential, and numerous solutions have been proposed [3,4]. These architectures address the less-stringent Bluetooth Low-Energy (BLE) standard, which depends on long intervals between advertising events to shorten the duty cycle of active operation, and have sacrificed RF performance like TX output level, sensitivity and blocking margins for ULP. Poorer sensitivity and low TX output level will decrease the coverage of IoT devices, and increased susceptibility to interferences will reduce the effectiveness of duty-cycling in BLE. Both cases will increase overall power consumption. On the other hand, conventional BT transceivers [1,2] rely on external RF components or large integrated passive devices (IPD) to deliver
