Multispectral Imaging CMOS Sensor
ProblemMultipixel image sensors are widely used in digital camera, LIDAR, medical imaging devices, and other equipment. For color image sensors, typically arrays of pixel elements are used for each pixel position. Light reaches each pixel element through a respective color filter, so each pixel element responds primarily to a single color, for example...

High-sensitivity low-energy thermal aware system for next generation integrated systems
ProblemTwo primary methods are used to achieve next generation integrated systems, a large number of deeply scaled devices and die stacking. High power densities and thermal issues such as long heat conduction paths are produced, which, in turn, can dramatically degrade performance, reliability, leakage current, and system robustness. To manage the...
