Description

This project will develop a full microelectronic ASIC design for a navigational grade front-end application specific integrated circuit (ASIC) that supports electrostatic and/or piezoelectric microelectromechanical (MEMS) gyroscopes operating in closed loop or whole angle operation. The ASIC proposed technology of choice is 180nm CMOS with high voltage transistor options. The high voltage transistors integrated the high speed transistors enable improvements in minimum detectable capactive charge sensitivity (10V operation). The proposed 180nm technology also affords minimum power consumption and die area due to the high performance high scaled transistors available. Temperature stability across the -40C to 85C range will be achieved using bandgap voltage references to set the bias points and operating conditions across the ASIC circuitry.
