Over the last four decades, the capabilities of integrated circuits have expanded at an exponential rate according to Moore’s law. As a result, their application space has also expanded from isolated server rooms, to desktops, to personal-area swarms, to within the body. The torrid pace has brought ICs to where they now face fundamental limits of energy, density, and performance. As a result, modern integrated circuit design requires new methods of scaling. Fortunately, since ICs have expanded into such a broad range of applications, there are many new opportunities to push their limits. These opportunities, however, are extremely diverse, requiring circuits that exploit the properties of new algorithms, new materials/devices, and new application characteristics.

Our research focuses on analog and digital integrated circuits with an emphasis on developing system platforms for emerging applications, especially where considerable computation and instrumentation is required but energy is severely constrained. Important examples include implantable and wearable biomedical systems and remote sensing and processing network nodes. To drive this, there are two broad research thrusts: 1) application driven circuits and algorithms for ultra-low-power systems and 2) platform components for low-power processing and communication in advanced and emerging technologies.

By focusing on specific application domains, electronic systems can perform rich sensor acquisition and efficient algorithm computation. We aim to develop analog topologies to acquire diverse, multi-channel biomedical signals and algorithm computation engines to extract specific correlations with physiological processes and conditions.  

Low-power processing and communication are critical means to reduces system power. To make their broad utilization increasingly more viable, we aim to develop SRAM, logic, and connectivity circuits to overcome emerging limitations in advanced technologies (e.g., nanometer CMOS) and alternate technologies (e.g., organic electronics).
