Abstract :
This paper describes the interface ASIC based on ring Schottky diode and TIA for MEMS gyroscope. The basic structure of interface ASIC is analyzed theoretically. 2MHz carrier is used to exert the mass and modulates the vibrational signal of MEMS gyroscope. This can amplify vibration signal by the frequency of carrier. The circuit is implemented in 0.18μm CMOS process and its size is 1.5×2.3mm2.
