Abstract

Traditional designs of high bandwidth frequency synthesizers employ the use of the PLL. The DDS provides many significant advantages over PLL approaches. Fast settling time, sub-Hertz frequency resolution, continuous-phase switching response and low phase noise are features easily obtainable in DDS systems. Although the principle of the DDS has been known for many years [Tie71], the DDS did not play a dominant role in wideband frequency generation until recently. Earlier DDSs were limited to producing narrow bands of closely spaced frequencies, due to limitations of digital logic and D/A-converter technologies. Recent advantages in integrated circuit (IC) technologies have brought about remarkable process in this area.
