Automated Data Check and Calibration System using Matrix Switch Prototype With Small Change of Line-Resistance

Abstract

In this paper, the hardware performance of a matrix switch prototype with small resistance deviation of each route and an automated data check and calibration system are described. The matrix consists of 12 rows and 3 columns, and the key switch connecting the rows and columns has a small on-resistance change even when the input voltage changes, so the matrix can keep the resistance deviation of each route small. Data check and calibration of circuits that are sensitive to errors due to lead-wires can also be automated with this matrix system to save time and reduce human error.
