Hi all,
I need to design a current source that will charge a capacitor, because the capacitor is very small( about 0.7 pF) I need a 1-10 nA current source, somebody can help me, and suggest how I can design such current source?
The circuit I'm designing measures changes in MEMS capacitor.
P.S
I need linear charge of the capacitor, so I need constant current source.
Leonid.
