无线供电的无垫单芯片无线电在65纳米CMOS中实现，用于物联网（IoT）和无线标签的应用。这种完全自给自足的毫米波无线电没有衬垫或外部组件（例如电源），整个无线电是一个尺寸为3.7 mm × 1.2 mm的单芯片。为了提供多址并减少干扰，它为RX/TX使用两个独立的毫米波频段，并集成两个天线以提供50厘米的测量通信范围。发射机使用改进的多脉冲脉冲位置调制（MPPM），在60 GHz载波上具有2 GHz带宽，用于通信数据序列以及本地时序参考。整个系统在待机收获功率低于1.5 μW的情况下运行，总数据速率达到12mbps。
A wireless-powered pad-less single-chip radio is implemented in 65 nm CMOS for applications in Internet of Things (IoT) and wireless tagging. This fully-self-sufficient mm-wave radio has no pads or external components (e.g., power supply), and the entire radio is a single chip with dimensions of 3.7 mm by 1.2 mm. To provide multi-access, and to mitigate interference, it uses two separate mm-wave bands for RX/TX and integrates both antennas to provide a measured communication range of 50 cm. The transmitter uses a modified Multipulse Pulse Position Modulation (MPPM) with 2 GHz of bandwidth on a 60 GHz carrier to communicate the data sequence as well as the local timing reference. The entire system operates with standby harvested power below 1.5 μW and achieves an aggregate data rate > 12 Mbps.
