Introduction

The integrated circuits and microsystems play a vital role in a variety of biomedical applications such as life-saving/changing miniature medical devices, surgical procedures with less invasiveness and morbidity, low-cost preventive healthcare solutions in daily life, effective chronic disease management, point-of-care diagnosis for early disease detection, high-throughput bio sequencing and drug screening, and groundbreaking brain-machine interface from deep understanding of human intelligence. In response to such strong demands on biomedical circuits and systems, a considerable amount of effort has been devoted to the research and development in this area, both by industry and academia.
