集成无线电设计的最新进展使得许多新的应用成为可能，其范围从可穿戴的医疗保健或健身监测器到物联网设备、结构完整性监测器等等。在许多这类应用中，设备尺寸和电池寿命至关重要。由于在小型传感节点中无线电通常会消耗很大一部分功率预算[1]，降低无线电功耗是减小电池尺寸或延长电池寿命的有效方法。降低无线电功耗可能具有挑战性，因为在功耗与诸如辐射输出功率、线性度、灵敏度、信道化能力和干扰灵敏度等性能指标之间存在重要的权衡。低功耗无线电设计往往为了追求低总体功耗而牺牲这些指标中的一个或多个。
Recent advancements in integrated radio design have enabled many new applications ranging from wearable health-care or fitness monitors to Internet of Things devices, structural integrity monitors, and beyond. In many of these applications, device size and battery life are of critical importance. Since radios often consume a significant portion of the power budget in small sensing nodes [1], reducing radio power consumption is an effective way to decrease battery size or increase battery life. Reducing radio power consumption can be challenging as there are important tradeoffs between power consumption and performance metrics such as radiated output power, linearity, sensitivity, channelization capabilities, and interference sensitivity. Low-power radio designs often sacrifice one or more of these metrics in the pursuit of low overall power consumption.
