Background:<\/p>\n

We\u00a0have created a new passive imager structure, which features a fully differential architecture, a low insertion loss electrical Dicke switch, and a flicker noise insensitive structure with digital multipliers and integrators. Unlike previous single-ended structures, the fully differential architecture facilitates single chip integration with digital baseband circuits by providing high immunity to common-mode and supply\/ground noises. The proposed digital multiplier and integrator significantly mitigate the CMOS inherent flicker noise issues by calibrating out the flicker noise contributions from all the RF\/analogue\/mixed-signal circuits. This is critical for the detection of the noise level of black body radiation. The low insertion loss switch further boosts receiver sensitivity with negligible noise figure degradation. The innovative system architecture leads to the highest responsivity of over 100 MV\/W to date on silicon, along with the best noise equivalent power of 26 fW\/\u221aHz on CMOS. We have published 9 papers and filed 3 patent applications in this area.<\/p>\n

The highlight from IET Electronics Letter states: \u201cPortable millimeter-wave passive imaging applications are a step closer with an innovative CMOS imaging chip architecture\u201d from Dr. Gu\u2019s group and her collaborators. The excerpt says \u201cPassive millimeter\/sub-millimeter-wave imaging has great potential in both military and civilian applications. By detecting black body radiation rather than needing a radiation source, a passive system is simpler and more flexible in its design. And the unique capability of millimeter\/sub-millimeter-wave imaging to see through fog, dust and concealed objects, along with its high sensitivity to water content and its non-ionizing nature, enables it to be applied in many fields such as defense, security, astronomy, environmental sensing, medicine and chemistry.<\/em><\/p>\n

With a wealth of potential applications for both passive and active imaging, the team is concentrating their efforts on the development of integrated solutions with reduced power consumption for portable and embedded functions. The success of these solutions will not only benefit existing applications, but will also open up new ones such as point-of-care medical diagnosis which could revolutionize today\u2019s medical diagnosis procedures. <\/em>\u201d<\/p>\n
