This issue of the IEEE Journal of Solid-State Circuits (JSSC) includes some of the highlights of the best papers from the 2011 Asian Solid-State Circuits Conference (A-SSCC), which was held at the Ramada Plaza Jeju Hotel, in Jeju, Korea, on November 14-16, 2011. The A-SSCC is one of the four conferences fully sponsored by the IEEE Solid-State Circuits Society, and this was its seventh appearance since its inauguration in 2005 in Taiwan. Following the past six successful A-SSCCs, this conference has been recognized as a prestigious technical event in the IC design field. The theme of the 2011 A-SSCC was "Integrated Circuits for Sustainable Future." Motivated by pursuing a quality life, intelligent electronics designed to enable healthy living and sustainable environment are playing increasingly important roles. This conference theme is a testimony of our - the IC design communities' - efforts in making the world a better place to be. The conference received 270 manuscript submissions from 25 countries, ofwhich 98 paperswere accepted after rigorous review process. After the conference, the technical program committee selected 15 outstanding papers for this JSSC Special Section. These papers contain full-length materials which describe the presented works in more detail than they were in the conference proceedings. These 15 papers include 6 analog and data converter papers, 6 wireline and wireless/RF papers, and 3 digital and SoC papers.
