该论文提出一种基于DCO的超低功耗、低电压相位跟踪接收机,采用直接解调和数据辅助载波跟踪技术,专为IoT应用设计。通过优化架构和电路,该接收机在0.85V电压下实现770pJ/b的能效,芯片面积仅0.3mm²,有效解决了物联网传感器网络电池更换/充电成本高的问题。
Johan Dijkhuis1, Robert Bogdan Staszewski2,3, Christian Bachmann1, Kathleen Philips1 Holst Centre / imec, Eindhoven, The Netherlands 2 Delft University of Technology, Delft, The Netherlands 3 University College Dublin, Dublin, Ireland 1 We propose an ultra-low-power (ULP) and low-voltage phase-tracking RX for IoT applications. Several popular standards are defined for IoT, e.g., IEEE802.15.4 and Bluetooth Low Energy (BLE), where they envision massive numbers of interconnected sensors; however, the cost of replacing/recharging batteries can become an impediment to their massive deployment. In this work, aggressively improving the transceiver energy efficiency, lowering the supply, and simultaneously reducing the cost (die area) of the design are our primary goals. Hence, we propose a digitally-controlled oscillator (DCO)-based phase-tracking RX, which efficiently combines frequency downconversion, channel selection,
