摘　　要：针对微机械隧道陀螺仪输出信号的特点,设计出陀螺仪隧道电流的检测及校准电路.同时从理论上对电路进行误差分析,并对电路的实际安装技术进行了讨论.最后通过实际电路验证了该设计的可行性.According to the feature of the output signal from micromechanical tunneling gyroscope, the circuits used to detect and calibrate the weak tunneling current are designed. Error of the circuits is analyzed theoretically, and at the same time, the operative technology is discussed. Finally, the feasibility of the design is proved by the result of the circuits that we had built.
