General Voltage Feedback Circuit Model in the Two-Dimensional Networked Resistive Sensor Array

Abstract EN

To analyze the feature of the two-dimensional networked resistive sensor array, we firstly proposed a general model of voltage feedback circuits (VFCs) such as the voltage feedback non-scanned-electrode circuit, the voltage feedback non-scanned-sampling-electrode circuit, and the voltage feedback non-scanned-sampling-electrode circuit.

By analyzing the general model, we then gave a general mathematical expression of the effective equivalent resistor of the element being tested in VFCs.

Finally, we evaluated the features of VFCs with simulation and test experiment.

The results show that the expression is applicable to analyze the VFCs’ performance of parameters such as the multiplexers’ switch resistors, the nonscanned elements, and array size.
