Imec开发出一款CMOS器件上低功耗79GHz雷达发射器

元器件交易网讯 2月21日消息,据外媒报道,比利时的半导体研究机构Imec开发出一款28nm的cmsos器件上的79GHz雷达发射器。

此雷达技术主要为驾驶员提供大于10cm的分辨率,应用于驾驶员辅助系统。Imec表示采用CMOS器件而不是砷化镓或者氮化镓太阳电池,可以降低高带宽和高载波系统力量,从而达更高的分辨率,更宽阔的视野和高角分辨率。

连续的电磁波雷达发射器供应电源为0.9v,输出电力却高达10dBm.消耗121mw。相位调制保证了高抗干扰,雷达信号多输入多输出。

Imec表示到2015年将建立一个完整的多天线系统。(元器件交易网 白玉涛译)

以下为外文:

Imec, the Belgium-based semiconductor research organisation, has created a 79GHz radar transmitter implemented in a 28nm CMOS device.

The target is millimeter-wave radar systems, offering resolution finer than 10cm, in next-generation driver assistance systems. Imec said the use of CMOS, rather than gallium arsenide or gallium nitride, could potentialy reduce the power of these high bandwidth and high carrier frequency systems needed to achieve the necessary resolution, wide field of view and high angular resolution.

The continuous wave radar transmitter hash an output power above 10dBm from a supply voltage of 0.9V. It consumes 121mW. Phase modulation guarantees high resilience against interference and enables code-domain multiple-input, multiple-output (MIMO) radar.

Imec said it will build a complete multi-antenna lab prototype by the end of 2015.
