| Abstract: | The FPGA-based phased-signal generator described in this paper meets the requirement of massive output channels and high resolution of HIFU. After experimental measurements, this phased-signal generator can output 256 channels of phase signals and each channel has a phase resolution of 2nS. The phased-signal generator also has many other advantages such as simple implementation method and high reliability. |
