摘要:: 为了提高SGS传感器的集成效果，对其供电电路和数字滤波器设计并开展实验验证。设计的SGS传感器采用基准稳压源ADR4550作为供电电源，选择精密运放ADA4622完成基准源的放大缓冲过程。设计的数字滤波器包括有限长单位冲激响应(FIR)滤波器与无限脉冲响应(IIR)滤波器，通过Matlab来封装函数FIR并采用经典方法实现加窗线性相位FIR滤波器的功能。实验验证结果得到：供电电源输出波形，输出电压噪声峰值在0.7 mV内，供电电源具备良好的稳定性。压电陶瓷的输出位移及其位移与输出电压的非线性误差在0.05%以内，均方根误差等于1.718 mV。

Abstract:: in order to improve the integrated effect of SGS sensor, the power supply circuit and digital filter were designed and tested.The SGS sensor in this design USES the reference voltage regulator ADR4550 as the power supply, and the precision operational amplifier ADA4622 is selected to complete the amplification and buffering process of the reference source.Digital filter design including finite length unit impulse response(FIR) filter and infinite impulse response(IIR) filter, Matlab to encapsulate function FIR and classical method to achieve the window linear phase FIR filter function.Experimental results show that the power supply output waveform, output voltage noise peak in 0.7mV, the power supply has good stability.The output displacement of the piezoelectric ceramics and the nonlinear error between the displacement and the output voltage are within 0.05%, and the root-mean-square error is equal to 1.718mV.
