该论文提出了一种工作于0.5V电压、功耗仅1.15mW、面积0.2mm²的Sub-GHz ZigBee接收机，支持433/860/915/960MHz ISM频段，且无需任何外部组件，解决了物联网超低功耗无线电的全球通用性和低成本问题。
UMTEC, Macao, China, 3 Instituto Superior Tecnico, Lisbon, Portugal 1 2 The rapid proliferation of Internet of Things has urged the development of ultralow-power (ULP) radios at the lowest possible cost, while being universal for worldwide markets. Both current-reuse [1,2] and ultra-low-voltage [3] receivers are promising solutions. [1] unifies most RF-to-BB functions in one cell for current-mode signal processing, resulting in a high IIP3 (–6dBm) at small power (2.7mW) and area (0.3mm2). However, outside the current-reuse cell, another supply is required for other circuits, complicating the power management [1,2].
