picoampere

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(HP4284A)进行C-V曲线测；以微安培(HP4140B)进行J-V曲线测。

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.

即使1mV的正向偏置之下，1N3595的漏电流一般小于1皮安，此电路响10pA或更大电流的测。
