Abstract
I / F converter are the circuit which can convert the current signal to the linear proportional frequency signal [1]. Actually due to various reasons there are some non-linear elements in the circuit. Paper use ADI´s ADuc847 processors as the main chip, and add the appropriate compensation circuit as peripheral circuits to compensate the non-linear elements. Firstly we sample the input and output data. Then we process the data by Matlab to obtain the compensation formula. Finally, we program to realize the compensation by the compensational circuit.
