Ultra-low-power biomedical circuit design and optimization: Catching the don't cares

To reduce healthcare cost while simultaneously delivering high-quality health services, developing new portable and/or implantable biomedical devices is of great importance for both health monitoring and clinical treatment. In this paper, we describe a radically new design framework for ultra-low-power biomedical circuit design and optimization. The proposed framework seamlessly integrates data processing algorithms and their customized ASIC implementations for co-optimization. The efficacy of the proposed framework is demonstrated by a case study of brain computer interfaces (BCIs).
