Design and implementation of phase detector on FPGA

This paper presents the design and implementation of a phase detector on a high speed field programmable gate array. The phase has been determined using zero-crossing detection approach. All the components used in the proposed design have been realized on the digital platform. Verilog and Xilinx ISE 12.4 design tool have been used for the development and verification of the design. The design is implemented on Virtex ML505 development board. The complete design has three principal modules namely; controller for analog-to-digital converter, zero crossing detection, and phase measurement. Real-time verification of the proposed design has been carried out with the help of Real time digital simulator and results are recorded on digital oscilloscope.
