Simulation and characterization for the non-linearity of multilayer ceramic capacitors with new equivalent circuits under Ac-field

Abstract

This paper describes examines the non-linearity of multilayer ceramic capacitors (MLCC) with new equivalent circuits. The electric charge quantity (Q) was measured as a function of applied voltage (V) under 16 V ac-field to validate the ferroelectricity of MLCC with capacitance of 1 μF. The Q-V curves predicted under ac-field using B2 spice software showed the non-linearity of ferroelectricity in the high ac-field. The Q-V curve predictions were in agreement with the experimental data for the MLCC.
