Design of Logic Control for Micro-power A/D with a Serial Interface Using FPGA

To realize the low-power consumption and miniaturization of the remote power quality monitor, a kind of parallel multi-channel acquisition scheme using micro-power A/D with a serial interface is presented. After the designing ideas of total acquisition scheme based embedded microprocessor is introduced in the paper, the implementation of complex logic control for the micro-power A/D using FPGA is given in detail, and the correctness of sequential design to control the A/D is verified by simulation experiments with EDA tool. The scheme also has great practical values for the design of portable test instrument.
