Are you sure you have an atto Farad capacitor? This is 10^6 below a pF, which is generally recognised as the value of stray capacitance in a well-constructed discrete circuit. If you really need to measure an atto Farad directly I would suggest using several GHz in a bridge circuit with suitable guard rings. Definitely beyond the scope of my experience. |

Here is a measurement technique which claims a resolution of 1aF. It is aimed at the measurement of on-chip strays. https://ieeexplore.ieee.org/document/5976854/?reload=true |
