Imec宣布用于5G的世界级低功耗IP模块诞生

比利时鲁汶,2017年9月6日 - 今天,在新加坡的Imec东南亚科技论坛上,世界领先的纳米电子和数字技术研究与创新中心imec将展示两款具有创纪录低功耗的关键构建模块,用于将来的5G应用。第一款是逐次逼近型模数转换器(SAR ADC),它指令周期快,体积非常紧凑,专为在6GHz以下頻段(4G / 5G)上运行的消费电子产品而设计,例如手机。第二款是具有射频(RF)相移和片上收发切功能的60GHz前端模块,针对5G固定无线接入和小蜂窝回传应用而开发感兴趣的公司可通过加入imec的产业联盟计划或获得知识产权许可,获取这两款构建模块。

 

5G mobile networks, promise massive connectivity through much higher data rates, lower latency and lower battery consumption than current 4G standards. To realize this, frequencies below 6GHz and also millimeter-wave frequencies, especially at the 57-66GHz unlicensed band, are explored, promising speeds of multi-Gb/s with low latency.

“Imec is developing novel IP building blocks for 5G, operating below-6GHz as well as in the 60GHz frequency band,” stated Wim Van Thillo, program director perceptive systems at imec. “Our portfolio includes record-breaking analog-to-digital convertors (ADCs), reconfigurable low-noise frequency synthesizers, millimeter-wave phased array transceivers, antenna modules and more. These building blocks show state-of-the art performance, excel in low-power operation and are low cost by leveraging scaled CMOS technologies. They give our partners a unique advantage in realizing their next-generation SoC for 5G wireless communication”

Targeting smartphone applications in the below-6GHz band, imec has developed a compact, low-cost, low-power and high-speed (300Ms/s) ADC that meets the requirements of multimode multiband 5G communication. The ADC is a SAR with a reduced core area of only 350µmx 325µm which is fabricated in 16nm CMOS. It achieves a dynamic low power consumption of only 3.6mW at 300Ms/s and low-frequency signal to noise and distortion ratio (SNDR) of 70.2dB at 204MS/s.

Imec also developed a compact, energy efficient and low-cost radio front-end (TRX) that operates at 60GHz. The chip features 8-way calibration-free beamforming at RF frequencies to support a large number of antennas, making the technology attractive for fixed wireless access and small cell backhaul. The on-chip transmit-receive switching allows to share the antenna array between transmit and receive mode. The 9.6mm2 chip is implemented in 28nm CMOS and consumes 231mW in receive and 508mW in transmit mode (0.9V supply).

These results are presented at ITF Southeast Asia (Sept 6, Singapore), one of imec’s leading high-tech events, offering an exclusive research and innovation perspective on the emerging opportunities of nanoelectronics and digital technologies. Under the theme “Tech solutions for a smart world”, imec presents innovations on hardware and software innovations that drive a smart society.
