在本文中，我们提出了一种超低功耗唤醒接收机前端工作在868/915 MHz ISM频段。它的目标是短距离的身体区域网络。其功耗仅为126 uW，包括低功耗片上环形振荡器。由于接收器的目标传输距离很小，最远可达10米，因此灵敏度与功耗之间存在权衡。这是通过去除LNA并使所有增益都处于低IF频率来实现的。接收器灵敏度为− 65 dBm，BER为0.1%。
In this paper, we present an ultra low-power Wake-up Receiver front-end operating in the 868/915MHz ISM band. It targets short distance body area networks. Its power consumption is only 126uW, including a low-power on-chip ring oscillator. Since the receiver targets small transmission distances, up to 10m, sensitivity is traded against power consumption. This is achieved by removing the LNA and making all the gain at the low IF frequencies. The receiver sensitivity is −65dBm at a BER of 0.1%.
