Guest Editorial - Special Issue on Selected Papers From BioCAS2009

T HIS special issue of the IEEE TRANSACTIONS ON BIOMEDICAL CIRCUITS AND SYSTEMS is devoted to topics from the 2009 IEEE International Symposium on Circuits and Systems (ISCAS 2009), held on May 24–27, 2009, at the Taipei International Convention Centre in Taipei, Taiwan. The IEEE ISCAS conference is the world’s premier networking forum of leading researchers in the highly active fields of theory, design, and implementation of circuits and systems. The conference received 1650 submissions from academic and industry authors. The final conference program accepted 809 papers from 5 continents and 40 different nations spanning 3 full days, with 102 lecture and 48 poster sessions covering 17 tracks represented by CAS Society technical committees, as well as the special session track and the track for live demonstrations. Topics presented at the conference span a wide range of exciting, state-of-the-art fields, and papers related to biomedical circuits and systems can be found in several different technical tracks, including analog signal processing, biomedical circuits and systems, cellular neural networks and array computing, circuits and systems for communications, digital signal processing, life-science systems and applications, nanoelectronics and gigascale systems, neural systems and applications, sensory systems, visual signal processing and communications, and the live demonstrations track. The contributions presented in this Special Issue cover a variety of modern and timely topics in the biomedical circuits and systems community. Beginning with a list of 63 papers that were highly rated by ISCAS 2008 reviewers, we distilled this to a small selection of journal-ready articles that showcase the state of the art within the BioCAS field. After a thorough peer-review process, it is our pleasure to present you with the final set of papers for this Special Issue on ISCAS 2009, which focuses on circuits and systems for neural and implantable technology. The selected contributions include papers in four areas:
