The use of millimetre wave (mmWave) technology in advanced driver assistance systems (ADAS) has grown tremendously in recent years. Applications have rapidly evolved, from comfort functions such as adaptive cruise control (ACC), to safety functions such as emergency braking, to newer applications such as pedestrian detection and 360° sensing.
There is also a shift in the industry toward the use of the 76 to 81GHz frequency band due to emerging regulatory requirements, larger bandwidth availability, smaller sensor size and performance advantages.
Traditionally, radar implementations used discrete components, but in today’s market more integrated solutions are becoming available. A complementary metal-oxide semiconductor (CMOS) integrating radio-frequency (RF) and analogue functionality, as well as digital control capability into a single chip reduces cost and form factor.
In addition, such a highly integrated solution also makes it efficient to implement advanced techniques that improve system performance and enables developers to meet functional safety compliance using on-chip processor-based built-in self-test (BIST) capabilities.
