I have a circuit, which is designed to use capacitor to hold the sampling voltage. But after sampling, the voltage drops quickly. Which means some current must go some path to ground to discharge the capacitor. I have already check my circuit, the only reason thing I found may be the ESD protection circuit would have some leakage current in my IC design.

However, I am not sure. Have anyone can help me to find the answer? Thanks.
