Apparatus for and method of measuring capacitance with high accuracy

摘要

For measuring a capacitance with high accuracy, a capacitance measuring apparatus includes a voltage source with a current limiting function for applying different voltage values to the capacitance, and an integrator capable of continuous integrating operation for repeatedly integrating a current flowing through the capacitance at given periodic intervals. There is also disclosed a capacitance measuring method that is carried out by the capacitance measuring apparatus.
