The ability of merging mechanical and electrical functions in the same substrate whose sizes range from micrometer to millimeter has created a new class of solid state device called MEMS (microelectromechanical system). MEMS achieves certain functions by electromechanical or electrochemical means. It generally consists of two basic components: a sensing and /or an actuating element and a signal transduction unit. However in almost all MEMS applications high performance analog and mixed signal integrated circuits are needed to convert the sensor signals for further processing and control. Currently these high performance application specific analog IPs are not available to our industry in an affordable manner. Therefore the objectives of this project are : 1) Develop a comprehensive analog IP library consisting all of the key technologies for several integrated MEMS sensor applications. These will include power management and on chip temperature sensing, low noise analog signal processing and conditioning, and low power data conversion, 2) Establish MEMS SOC specific mixed signal integration and design verification capability as a design service to industry 3) Perform product reliability and qualification for ready commercialization of ASTRI's IPs. The project team will leverage their proven expertise in areas of power management, signal processing and data conversion and optimalize a family of reusable IPs for integrated MEMS sensor applications. The availability of such technology will enable our industry to develop integrated circuit products for this growing market.
