摘要

为了实现真正的移动性，可穿戴电子设备应该能够根据环境自行供电。体上热电(~ 50 μ W/cm2)是一种成熟的能源，但其输出电压极低且不恒定(0.05至0.3V)，阻碍了其实用性。由于超低电压(ULV)升压转换器的功率效率有限([1]中为64%)，人们对开发可以直接在能量收集器输出处工作的超低电压无线电越来越感兴趣，从而减少了能量浪费和主动睡眠延迟。[2]中的2.4GHz接收器验证了0.3V的工作，但是非标准设计，没有I/Q解调。此外，它的重点是有功功率(1.6mW)，假设它的0.3V电源是恒定的。

24.4 A 0.18V 382µW bluetooth low-energy (BLE) receiver with 1.33nW sleep power for energy-harvesting applications in 28nm CMOS

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.
