A Viterbi School paper presented at last year's IEEE International Solid State Circuits Symposium has been voted the best of the 125 papers offered at the event, the major annual meeting in the subject.

The paper, entitled "A Fully Integrated 24GHz 4-Channel Phased-Array Transceiver in 0.13um CMOS Based on a Variable-Phase Ring Oscillator and PLL Architecture" by graduate student Harish Krishnaswamy and Asst. Prof. Hossein Hashemi of the Ming Hsieh Department of Electrical Engineering, received the Lewis Winner Award, given to every year's ISSCS outstanding paper at the subsequent gathering.

Hashemi and Krishnaswamy received their medallions February 4 at the 2008 ISSCS, held in San Francisco.

The award recognized a chip built with well-known, cost effective CMOS technology that functioned as a send-and-receive radar receptor, an ability that has previously required much more expensive trace-metal semi-conductors.

This chip has already attracted the attention of automakers for possible use in car radar, because 10 such devices could be installed for a little more than $100 — less than a tenth of what single devices now in use for self-parking and blind spot detection systems cost.

Hashemi believes the same chips can be used to create Local Area Networks with far greater capacity than existing units.

The award is considered extremely competitive and past winners include names like that of Nobel Laureate Jack Kilby.

Hashemi, who came to the Ming Hsieh department in 2003 after winning his Ph.D. from Caltech, this year was named to the Gordon S. Marshall Early Career Chair.
