چکیده :

This research has designed and implemented a medium-speed and high-precision data logger using ZYNQ XC7Z020 FPGA and AD7768 ADC. The sampling rate of kSPS and high-speed data transfer via Ethernet were the goals of this research, and the implementation results indicate the success of this project. In this system, ADA4807 amplifiers were used to amplify analog signals, ensuring that input signals with gains between 1 and 10 were sent to the ADC. The delta-sigma architecture of the AD7768 guarantees 24-bit resolution and significant noise reduction. After digital processing in the FPGA, the data were transmitted to the computer through the Ethernet port. Tests demonstrated that the system is capable of real-time sampling and transmission of various signals with high accuracy and efficiency, making it suitable for industrial applications, measurements, power quality analysis, and medical monitoring.
