摘　　要：针对硅陀螺中信号发生器的技术指标要求,设计了一种基于文氏桥振荡器的正弦信号发生器。正弦信号发生器由文氏桥RC振荡器、整流器以及PI调节器三部分构成。论文分析了各类电路性能的优缺点,并计算了各部分电路及运算放大器的技术参数,最后分别进行了不同电压值的瞬态仿真和稳态仿真、温度稳定性仿真、幅值稳定性仿真、谐波失真仿真。结果表明,仿真值与理论值一致,符合设计要求。Ac：ording to technical index requirements of signal generator in sihcon gyroscope,a sinusoidal signal generator based on Wien bridge oscillate r is designed. Sinusoidal signal generator is composed of Wien bridge oscillator,RC rectifier and PI regulator. Firstly,the ad- vantages and Cisadvantages of each circuit performance are analyzed,and the technical parameters of each part of the circuit and operational amplifier are analyzed and calculated. Then, transient simulation and steady state simulation, temperature stability simulation, amplitude stability simulation and harmonic distortion simulation are carried out respectively. The simulation results show that the simulation values are consistent with the theoretical values and meet the design requirements.
