Design of Phase Shift Signal Generator

Abstract

A phase shift signal generator which has high precision and whose phase can be easily and digitally controlled is designed through utilizing DDS technology. A method which can replace complicated hardware description language programming through calling modules and setting parameters is proposed. The designed phase shift signal generator passes waveform simulation under Simulink and SignalTap Ⅱcertification, and the results obtained on the FPGA board are correct. The DSP Builder is utilized to design the phase shift signal generator, which reduces the difficulty of the design and shortens the design time.
