Dr. Brian Floyd
Brian Floyd have been awarded $300,000 by the University of Texas - Dallas for research on Built-in Test for Power-Efficient Millimeter-Wave Phased Arrays. The award will run from March 1st, 2011 to February 28th, 2014.
Research Abstract - The large available bandwidth and/or the small wavelengths at millimeter-wave(mmWave) frequencies make possible large-volume applications such as 60-GHz communications, 77-GHz radar, and 94-GHz imaging. Within these applications, there are requirements to either steer a beam around an obstruction (60 GHz) or focus energy in a specific direction (77/94 GHz); therefore, mmWave phased-arrays in silicon is an important and growing commercial research area. Critical work remains related to power reduction of the array elements and cost-effective test, both to be pursued in this project. First, significant power reduction is needed for the phased arrays to make them viable in battery-powered devices or to reduce heat-sinking requirements. Second, since test can dominate overall cost, built-in-self-test techniques must be developed for the phased array to reduce the time of test of a complete array, to reduce the need for mmWave test equipment, and to enable phased-array manufacturing test at both wafer and package-level. In this project, a low-power 60-GHz four-element phased-array transmitter prototype with built-in-self-test will be developed in 0.12-micrometers SiGe BiCMOS technology and then scalable test techniques will be developed for this demonstration platform which are applicable to 60-GHz radios, 77-GHz radars, 94-GHz imagers, and even >100-GHz sensors.
