A prototype FPGA for subthreshold-optimized CMOS (abstract only)

Published: 27 February 2011 Publication History

Abstract

Field-programmable gate arrays (FPGAs) are frequently used in low power systems because they can implement the same functionality as a microprocessor in a more energy-efficient manner while still offering the benefits of low development time and cost relative to an ASIC. Similar advantages for FPGAs may be found in ultra-low power applications operating at subthreshold supply voltages, where performance is sacrificed in favor of increased energy efficiency. Process technology research has demonstrated the benefits of tailoring device design to subthreshold operation. Subthreshold FPGA research is only beginning, and has yet to consider use of subthreshold-optimized devices. A simplified FPGA implemented in subthreshold-optimized CMOS is presented. The results obtained show that this technology provides the capability to implement an FPGA suitable for ultra-low power applications consuming tens to hundreds of microwatts of average power.
