<p>PROBLEM TO BE SOLVED: To correct the dispersion of an integral constant. SOLUTION: Reference voltage Vr is integrated only in a period Ta by using the integral constants of C1.R1 and integral voltage is obtained. Then, integration is executed in an opposite direction only in a period Tb when volt becomes original one by using the integral constant of C1(R1+R2) and reference voltage Vr. The ratio of the design value of the period Tb and an actual value is obtained. An integral period when integration is executed by the integral constant of C1(R1+R2) is corrected based on the ratio.</p> |
