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.

另感容阻计量仪(HP4284A)进行C-V曲线量；微安培计量仪(HP4140B)进行J-V曲线量。

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正向偏置之下，1N3595漏一般会小于1皮安，此路不会影响10pA或更大量。
