摘要
提出了一种利用高阶神经网络拟合ＶＦ型ＡＤＣ输出特性的新方法，实现了ＶＦＣ１１０芯片在４ＭＨｚ满量程时的非线性估计．设计了两种动态在线标定电路用于提高采样精度．该方法也可用于类似场合的传感器输出特性的非线性拟合．
A new method is presented in this paper for fitting VFC*ss (voltage to frequency converter) output functions by using high order neural networks. The nonlinear estimation is implemented when the VFC110 is used at a full scale output frequency of 4 MHz. Two kinds of on line dynamic calibrating circuits are designed to improve the sampling precision. This method can also be applied to different industrial applications.
