旧金山,2018年2月11日 – 在2018年旧金山国际固态电路会议上,世界领先的纳米电子和数字技术研究与创新中心imec与高级半导体解决方案主要供应商Renesas Electronics Corporation联合发布了低电压(0.8V)超低功耗蓝牙5收发器,用于物联网应用领域。低电源电压(同类最低)可延长电池使用时间(最多可提高 50%)。
 
In the Internet of Things (IoT), numerous tiny sensor nodes are embedded in our environment. Reducing the power consumption and enabling operation at low supply voltage of IoT radio transceivers is key to enable reliable multi-year battery life of the billions of IoT devices in our environment. Furthermore, new applications are empowered by reducing power consumption and supply voltage, such as leave-behind sensors or wearables.
 
Imec, together with Renesas, developed a fully-integrated, highly energy efficient BT5 transceiver which showcases the best RX figure-of-merit (FoM) and the lowest supply voltage among the state-of-the-art (0.8V). A low supply voltage of 0.8V is beneficial because it extends battery life by up to 50%, reduces the complexity of the power management unit, and allows the use of a wider range of energy sources such as energy harvesters.
 
The transceiver consists of a novel phase-tracking RX, a digital TX based on an all-digital PLL (ADPLL) and a PHY-layer digital baseband. A hybrid loop filter enhances interference tolerance, in conjunction with precise frequency control enabled by the ADPLL. The receiver fronted achieves a sensitivity of -95dBm, while consuming only 2.3mW (non-duty-cycled) at 0.8V.  The transceiver chip is implemented in 40nm CMOS, with a core area of only 0.8mm2, including on-chip matching.
 
“This world-class BT5/BLE transceiver for IoT applications is the result of a successful collaboration with Renesas,” commented Kathleen Philips, Program Director at imec/Holst Centre for IoT. “We are constantly looking for ways to improve battery lifetime of IoT sensors and radios and a low supply voltage is yet another key element in the roadmap towards successful IoT radio solutions.”
 
“Renesas has been producing high-performance devices leveraging low-power wireless communication technology, which will play a key role for expanding the upcoming wireless IoT business moving forward,” said Shin Saito, Senior Director, Industrial Analog & Power Business Division, at Renesas. “Renesas believes that by jointly developing with Imec, we can achieve a more innovative system architecture, enabling a further leap for ultra-low power wireless technology and the wireless IoT market.”
