NXP to Focus on All CMOS Radar Future
From GaAs to SiGe, now to CMOS?
The first commercial radar systems of the late 1990’s were based on GaAs chips. But then Infineon started developing systems based on bipolar process SiGe chips. So did Freescale. Those SiGe radar chips are already designed into radar collision warning systems.
Reportedly, automotive radar developers have already warmed up to SiGe radar chips and begun switching from GaAs. But here’s a big question: Will the new millimeter-wave sensors made in plain CMOS prompt them to switch again — this time from SiGe to CMOS?
That’s the big market shift NXP is betting on. And certainly NXP isn’t alone thinking along these lines.
About a year ago, IMEC announced a 79GHz radar transmitter implemented in 28nm CMOS and designed for automotive radar systems. At that time, IMEC, which developed it in collaboration with Vrije Universiteit Brussel, called it “the world first,” explaining, “With an output power above 10dBm, the transmitter front-end paves the way towards full radar-on-chip solutions for automotive and smart environment applications.”
Asked if NXP’s Dolphin was spun out of IMEC’s development, Reger said no. He said it’s an internal project three years in the making.
