📄 原文摘要

near-threshold regions minimizes dynamic power consumption and achieves better efficiency [1]. This technique is widely used in energy-efficient applications, and is especially beneficial for wirelessly powered devices such as wearable electronics, biomedical implants and smart sensor networks. Such devices have long standby times and battery-less operation is highly desirable. As shown in Fig. 20.5.1, for a typical wireless power transmission system, there is a gap between the rectified VIN (>2V) and the low supply voltage VOUT (<700mV) for powering up energy-efficient digital circuits. To bridge this voltage gap without sacrificing compact size, fully integrated power converters with a low voltage conversion ratio (M=VOUT/VIN) and high efficiency are needed. However, a low M
