A cost-effective A/D electronic system based on the simplified structure $\Sigma$–$\Delta$ is presented. This system can reproduce the external voltage applied to a nonlinear capacitor and derive the electric current across it. Moreover, polarization vs applied voltage curves can also be measured by integrating electric current in real time. The application of this system to the evaluation of liquid crystal display pixels is demonstrated.
