英文摘要 | This paper describes an interface circuit design for monolithic CMOS-MEMS gyroscopes, based on a novel differential difference amplifier (DDA) with high gain, low temperature and process dependence, low noise, and low power consumption. The DDA achieves a 4 fF equivalent transcapacitance with a 0.01%/?? C temperature variation. The DDA-based interface circuit has been integrated with a z-axis gyroscope on a foundry CMOS chip. A 4.5 zF/ ??Hz input-referred noise is achieved at 2 kHz, with a total power consumption of 4.25 mW. The gyroscope is fabricated with a post-CMOS bulk micromachining process and the device achieves a sensitivity of 1.2 mV/??/s and a noise floor 0.05??/s/ ??Hz. ? 2006 IEEE.; EI; 11; 2740-2748; 11 |
