VF-NSE method measurement error analysis of networked resistive sensor array

In this paper, we present a measurement error analysis of the voltage feedback non-scanned-electrode (VF-NSE) method for the 2-D resistive sensors array that shares row and column connections for simplifying interconnections. A mathematical voltage expression for the VF-NSE method has been analytically derived and verified by the circuit simulations, which is affected by the multiplexers’ resistor, the column adjacent elements and the row adjacent elements. Based on this analysis of the VF-NSE method with the sample resistor connected to the voltage source, we examined and proved that the voltage expression is general for analyzing the effect of the multiplexers’ resistor, the column adjacent elements and the row adjacent elements in the networked resistive sensor array.
