| Abstract: |
| The performance comparison of the ultrahigh speed phase/frequency discriminator AD9901 with E12540 shows the advantages of the AD9901.In addition,a brief analysis of the phase detection"dead zone"is made.Finally,the design of basic phase-locked loop circuits including AD9901 is given with emphasis on some designing rules.The experiment result is also presented. |
