The team is also working on a new scheme to connect multiple CMOS radar front-end chips via automotive Ethernet, so that they work as one. NXP's Dophin operates on 80GHz band, "plus or minus a few GHz," making it work between 77GHz and 81GHz, according to Reger. — Junko Yoshida, Chief International Correspondent, EE Times. Abstract. A novel CMOS impulse radar for CMOS implementation is proposed exploring the concept of swept-threshold sampling. Time-domain signal processing with counter-based integration in parallel.
