“…As wide spread and rapid development of an internet technology has led to the change of industrial and system management structures, sensing process will play a lot of significant roles. Such sensing-then-sharing process is a part of a framework such as Industry 4.0, and further demands for the sensor systems will appear along with this rapidly-evolving framework [1], [2].…”

There is a trade-off between resolution and acquisition range of voltage while performance of feedback control depends on the resolution. Many signals in motion control change quickly with various range and hence both of saturation avoidance and high-resolution data-acquisition are one of the challenges. This research proposes a multi-amplification technique which provides a wide-range and high-resolution A/D conversion. A high-frequency-operated circuit and a fast processor on an FPGA are developed and then a signal-processing module is designed. Experimental results show the validity of the module.
