For electrical properties of MOS capacitors, the C-V curves were obtained by LCR meter (HP4284A), and picoampere meter (HP4140B) was used to measure the J-V curves.

另外以电感电容电阻量(HP4284A)C-V曲线量测；以微安培量(HP4140B)J-V曲线量测。

The leakage of the 1N3595 diode is generally less than one picoampere even with 1mV of forward bias, so the circuit won't interfere with measurements of 10pA or more.

1mV的正向偏置之下，1N3595的漏电流一般会小于1皮安，此电路不会影响10pA或更大电流的测量。
