Multi-Switch Integrated Circuit Design for Micro Sensors of Smart Factory

In this study, micro multi-switch integrated circuits (IC) for display boards for smart plant sensors were designed and manufactured using a 0.25 µm CMOS process. The switch chip is composed of four single pole single throw (SPST) switches and eight single pole double throw (SPDT) switches, and it was found that the size of the semiconductor IC designed using the simulation with layout effects and a circuit at a transistor level satisfied the target performance even with the process, voltage, and temperature (PVT) variations.
