Electrochemical current- and voltage noise as a function of time of unbiased Au electrodes in aqueous 100 mM KCl solution.

The electrode areas are 2 mm2, 6 mm2 and 10.5 mm2. The current noise increases with electrode area from 1 pApp to 10 pApp, while the voltage noise decreases with electrode are from 0.7 μVpp through 0.5 μVpp to 0.3 μVpp. The current amplification was 5 nA/V and the voltage gain was 1000.
