    摘要: PROBLEM TO BE SOLVED: To measure DC bias-capacitance characteristics by shortening the inspection time necessary per capacitor without need for a dedicated inspecting instrument.
    SOLUTION: A measuring apparatus 1 includes: an element connection 4, a limiting resistor 3, a DC bias source 2, a current measuring instrument 5, and an arithmetic part 6. The element connection 4 is connected with a ceramic capacitor 50. The limiting resistor 3 is a known resistance and connected to the ceramic capacitor 50 in series. The DC bias source 2 applies a known DC voltage to a serial circuit 7 composed of the limiting resistor 3 and the ceramic capacitor 50. A current measuring instrument 5 measures a current instantaneous value of the serial circuit 7. The arithmetic part 6 acquires a current instantaneous value at known time intervals, derives a capacitance instantaneous value of the ceramic capacitor 50 based on the current instantaneous value as well as a voltage instantaneous value applied to the ceramic capacitor 50 based on a DC voltage, a resistance value and the current instantaneous value, and determines a capacitance value of an element to be measured corresponding to the DC voltage value from the voltage instantaneous value and the capacitance instantaneous value.

    摘要: PROBLEM TO BE SOLVED: To simply measure the dielectric constant of a liquid in a simple manner, and to improve the measurement accuracy.
    SOLUTION: An apparatus for measuring the dielectric constant of a liquid includes a storage space 11, where the liquid is inserted into a conductive container 1, and the container serves as the first electrode. The opening 11a of the storage space 11 is sealed with a lid 2, having a core wire 25 serving as the second electrode that protrudes. During the measurement, a measurement system is calibrated by an open-type, short-circuited and loaded calibration lids 41, 42 and 43 in a shape which is similar to that of the lid 2. In addition, a fringe capacitance regarded as a measurement error is measured, in advance, by means of the calibration lid 41, and the accuracy in measuring the dielectric constant is improved by subtracting the error due to the fringe capacitance from the actual measurement result.

    摘要: PROBLEM TO BE SOLVED: To provide a parasitic component measuring device and a parasitic component measuring method capable of improving test accuracy of a high-frequency device or a high-frequency IC, and suppressing complication of an inspection system.
    SOLUTION: A capacity value of a variable virtual capacitance is adjusted so that a Smith chart of a circuit to be measured formed by connecting to a transmission line, an inductor to be measured having a known inductance value agrees with a Smith chart of a virtual equivalent circuit including a same-value virtual inductor having the same inductance value as the inductor to be measured, and the variable virtual capacitance connected to the same-value virtual inductor, capable of adjusting a capacity value. The capacity value of the variable virtual capacitance when the Smith chart of the circuit to be measured agrees with the Smith chart of the virtual equivalent circuit is calculated as a capacity value of a parasitic capacitance of the transmission line, to thereby measure the parasitic capacitance of the transmission line.
