The General and Technical Program Chairs and Organizing Committee of the 2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS 2015) are delighted to announce that MWSCAS 2015 will be held in Fort Collins, Colorado from August 2 to 5. MWSCAS is one of the oldest circuits and systems conference sponsored by IEEE Circuits and Systems Society. We are delighted to bring MWSCAS back to Fort Collins after 50 years since it was held in Fort Collins in 1965. Fort Collins has grown and transformed itself significantly since then. The city has been named several times by Money Magazine as one of the top places to live in the country. Fort Collins has a thriving arts scene, eclectic shops and restaurants, hundreds of miles of walking and biking paths, and a plethora of outdoor activities. The city and the surrounding area are often dubbed as "The Napa Valley of Beer", boasting many microbreweries that are nationally renowned. The Rocky Mountain National Park, located just outside of Estes Park, is only 45 minutes away from Fort Collins. It is perfect for a day of hiking, biking, a scenic drive or just sightseeing which may include elk, deer, and if you are lucky a moose or bear. Fort Collins is also home to many leading circuit and system design companies, such as Intel, AMD, HP, Texas Instrument, LSI Logic, Broadcom, Avago, and many more. Fort Collins is about 60 miles from Denver and is served by the Denver International Airport (DIA), one of the busiest in the world. There are many options to travel from DIA to Fort Collins. The most convenient way is to use Super Shuttle and Greenride. Both companies run frequent shuttles between DIA and Fort Collins. The shuttle vans pick up and drop off passengers at Fort Collins Hilton and at the transit center of Colorado State University. All shuttle services use toll road so that the time it takes to and from DIA is more predictable (60-70 minutes) regardless of traffic conditions in Denver. We encourage perspective authors to submit original work on all aspects of circuits and systems to the 58th IEEE MWSCAS. We are looking forward to welcoming you to Fort Collins, Colorado, in 2015.
