초록
In this study, a method is suggested to design the A/D conversion system which has high resolution to convert load cell signal. First, hardware was designed to reduce the offset voltage of integrator and comparator. And then, a calibration software technique was performed to obtain the stable data from A/D converter. The optimal parameters of each elements in the circuits was selected using the SPICE simulation. The main advantage of our method is high precision A/D converter can be constructed with low cost and high confidence. Therefore proposed method is expected to be used in the industrial field where a high precision measurement is required.
