"Connecting the analog world with the digital"
The real world is analog, but more and more information processing takes place in the digital sphere. This holds true in all areas of electronics application, and in particular in automotive electronics. Against this backdrop, it is obvious that the companies controlling the transition from one to the other sphere are of increasing importance. Analog Devices (ADI) is such a company. eeNews Europe spoke with Stefan Steyerl, Director Sales Mobility & Transportation for ADI EMEA.

But nothing goes without challenges: RFCMOS makes it more difficult to build high performance systems with sufficient output power to look far into the distance and thus push the phase noise to an acceptable level and finally to achieve the desired high resolution - all this is generally more difficult to implement in RFCMOS than in SiGe technology. When we decided to switch to RFCMOS, we decided to achieve at least the performance of SiGe from the beginning. With our current 28nm RFCMOS chipsets we have achieved this. This enables us to map the high performance systems described above onto an RFCMOS chipset. With this technology, it is easier to detect a child who suddenly steps onto the road between two vehicles - the higher accuracy helps. And the radar sensor can look further into the distance and detect obstacles earlier. For example, obstacles lying on the road - for automated driving it is also important to know how high such obstacles are. At heights of up to 7 cm, the vehicle simply drives over them; at higher obstacles, the control systems have to brake or drive around them. The sooner you recognize something like this, the more time the automatic has to react.

eeNews Europe: Do such systems also detect obstacles that appear a little higher above the road, such as the famous crosswise standing truck?

Steyerl: That depends on how the radar system is set up and whether I also measure the height via the number of channels and not just in the horizontal. We can also implement such systems with our technology.
