Abstract:
This paper introduces the design of phase-shift signal generator based on FPGA and Verilog HDL.It takes advantage of the principle of DDS and the embedded memory block of FPGA to store the waveform data.The phase-shift signal generator uses two D/A converters to generate two channels of phrase-shift signal and original reference signal that are of the same frequency in the arbitrary waveforms,for instance,sine wave,triangular wave,and square wave.Except for DA converters and its related circuits,all the functional modules are accomplished in a single FPGA.This design has the advantages over traditional phase-shift signal generator of high frequency resolution,a pure frequency spectrum,ease implementation and low cost.
Key words: phase shift signal;FPGA;DDS;digital control
