| Abstract: | For the characteristic of weak output current, large noise in the photoelectric signal detecting of the fiber-optic gyro, an analog selection integral circuit is designed for I/V conversion .The analog selection integral circuit with a high precision switching integrator is verified. The experimental results show that , this method reduces the random walk coefficient effectively. |
