提出了一种在28nm CMOS工艺下实现的0.18V超低电压蓝牙低功耗接收器，总功耗仅382μW，睡眠功耗低至1.33nW。该接收器可直接从能量收集器（如热电发电机）供电，避免了升压转换器的能量损耗，解决了超低电压下无线接收器的高能效运行问题。
Instituto Superior Tecnico, Universidade de Lisboa, Portugal 1 2 For true mobility, wearable electronics should be self-powered by the environment. On-body thermoelectric (~50μW/cm2) is a maturing energy source but delivers a deeply low and inconstant output voltage (0.05 to 0.3V) hindering its utility. With the limited power efficiency of ultra-low-voltage (ULV) boost converters (64% in [1]), there is a rising interest in developing ULV radios that can operate directly at the energy-harvester output, reducing the waste of energy and active-sleep latency. The 2.4GHz receiver in [2] validates 0.3V operation, but is a non-standard design without I/Q demodulation. Also, its focus is on the active power (1.6mW) assuming its 0.3V supply is constant. This receiver (Fig. 24.4.1) aims at the BLE standard, consuming just 382μW at 0.18V, and can tolerate 50% variation of its energy-harvesting supply (VDD,EH) up
