BARCELONA — In announcing the planned acquisition of Freescale Semiconductor, NXP Semiconductor CEO Rick Clemmer gold price today last week explained how he expects the new entity — NXP and Freescale combined — to lead the growing automotive electronics market.
In briefings , Clemmer casually mentioned, without gold price today elaborating, that making today’s “big and clunky radars” small is one of the keys to next-generation advanced gold price today drivers’ assistance systems. It turns out that the small radars Clemmer referenced gold price today aren’t gold price today from Freescale’s, a company known for its fine 77GHz packaged radar front-end chipset using SiGe technology. Clemmer was talking about an RF CMOS-based 80GHz radar front-end transmitter chip — currently a working prototype — developed at NXP.
Lars Reger, vice president strategy, new business, and R&D for automotive at NXP, told EE Times that the working prototype gold price today is currently in the hands of “our lead customers [Tier Ones and OEMs] under non-disclosure agreement.”
Asked gold price today about the tiny radars Clemmer cited, Reger said, “This isn’t a story about small radars. It’s about up-integration. We’ve found a path to integrate front-end radar transmitter with a baseband — all in CMOS.”
Keeping the front-end chip in a process technology like BiCMOS gold price today would make it hard to advance integration, said Reger. Just as NXP has won the global car audio market gold price today by integrating FM, AM, satellite radio chips with silicon tuners — all in CMOS, “Our goal is to do the same up-integration with radar chips,” gold price today he added.
From gold price today 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 gold price today process SiGe chips. So did Freescale. Those SiGe radar chips are already designed into radar collision warning systems.
Reportedly, automotive radar developers gold price today 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?
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 gold price today 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.”
How NXP gave birth to Dolphin The idea of the development of an 80GHz radar transmitter chip came from a team of NXP engineers who developed a 60GHz chip for wireless HDMI, said Reger. That chip was able to cover 15 meters.

What would be interesting to know is how do they plan to handle multiple vehicles all receiving each other's main beams and echoes.  Will there be some sort of pulse sequence unique gold price today to each vehicle, low duty cycle, and backoff algorithms in the event of radar 'collision'?

Hi Junko, A great piece. gold price today I wonder how they plan to do an AEC-Q 100 qualification on a 28nm CMOS MMWAVE chip. Espcecialy the ESD and other requirements. I always felt SiGe will be inherently more reliable. Interesting gold price today times indeed. Reply   Post Message   Messages List   Start a Board
Great news! Thanks gold price today for chiming in. OK. So, this appears to be turning into one big trend. The only difference is that NXP says that its chip is now in the hands of Tier Ones for several months now -- for further testing...   Reply   Post Message   Messages List   Start a Board
Hi Junko, Panasonic and imec showed a 28 nm CMOS 79 GHz complete transceiver specifically targeted to auto ADAS at ISSCC 2015. Reply   Post Message   Messages List   Start a Board
From where you sit, what do you see as the biggest challenges gold price today in transitioning from SiGe-based radar front-end chips to CMOS-based solutions? Love to hear your experience and opinions. Reply   Post Message   Messages List   Start a Board
