Paper Abstract

Phase-locked frequency multiplying technology is utilized to amplify 10MHz signal to 640MHz. Pulse inhibition method is then exploited to make high-frequency signal have a phase shift of 2π. 20MHz signal with 2π / 32 phase shift is output after 5 times flip frequency division. In order to optimize electromagnetic compatibility, signal integrity and power integrity of a high-speed circuit, system simulation is performed using HyperLynx, a specially EDA simulation software. A whole printed circuit board (PCB) was made under the guide of optimized simulation results. Phase-shift experiments show that the output of high-frequency phase-shifting circuit system is two-way signals with a frequency of 20.0001 MHz with 1.8ns time difference, i.e. two signals with 12.96°phase difference are obtained.
