IME’s research teams have been awarded the gold and bronze prize at the inaugural Chip Design Competition, held in conjunction with the biennial International Symposium of Integrated Circuits (ISIC) 2011, one of the world’s major conferences in the area of integrated circuits engineering. Scoring the Gold award is the team led by Dr Xue Rui-Feng (in picture, third from left), for their creative and innovative design of an ultra-low-power wireless implantable blood flow sensing microsystem for vascular graft applications. Another team led by Dr Hu Sanming was one of the bronze award winners for their design of a 77-135GHz Down-Conversion IQ Mixer for 10Gbps Multiband Applications.
The winning entry from Dr Xue’s team is a chip that provides sensor data on the blood flow in patients from within the body. This data can trigger an instant warning to the doctors upon detection of abnormal blood flow in the patient. The chip is designed with two unique features - the wireless power and data transmission, and it can be implanted into the human body.
The bronze award winning design is a universal frequency-conversion circuit which took a year to develop. Without any design change or bias adjustment, this chip can be used in different millimeter-wave systems including 77/79 GHz automotive radars, 94 GHz high-resolution active imaging, and 122/135 GHz high-data-rate communications.
The competition saw more than 40 submissions from around the world and narrowed down to 12 finalists from India, Japan, Singapore, South Korea, Sweden and Taiwan. The submissions were appraised on the criteria of productivity, novelty, reliability and power efficiency of their chip design.
