2ed Pulsed CV measurement, high-k material, Data

A negative feedback operational amplifier is used in today's pulsed CV measurement. This circuit has more accuracy than previous design.

Pictures below show some settings and waveforms on oscilloscope. Data recorded in the experiment can be found at last. Voltages used are 4V, 4.5V, 5V, 5.5V and 6V. The sample which is a high-k capacitor was broken after the first pulse under 6V.
