Abstract

The parallel plate capacitor has a simple structure.In order to ensure the precision of the capacitor

a shielding structure is usually used to avoid the interference of external stray capacitance.In this paper

the shield structure

which commonly used in capacitive voltage divider

is analyzed by using Ansys modeling and simulation

and a new multi-layer shielding structure is proposes.This method can achieve good effect verified by simulation.
