Definitions

  • the pulse width of both the first type of pulse and the second type of pulse is proportional to the phase difference detected between the reference signal and the feedback signal, (thereby causing the phase frequency detector 110 to provide a linear phase difference response).
  • the detection of frequency difference as well as phase difference between the two inputs to the phase frequency detector 110 is provided by the phase frequency detector 110 for example to allow for correction of the frequency difference that occurs when starting up the PLL 130 or when switching channel frequency of the PLL 130, e.g. when the PLL 130 is used in a radio transmitter, e.g. by changing the value of the number M referred to above.
  • the VCO tuning and resonating block 112 adjusts an output frequency F OUT of a signal it produces to be equal to a desired value.
  • the value of V O U T is related to the values of the divisor number M and the frequency of the reference signal provided by the reference oscillator 102. The values of these parameters are therefore selected in design of the synthesizer 200 to give a desired output frequency F OUT -
  • the VCO active block 116 amplifies the signal of frequency FOUT produced by the VCO tuning and resonating block 112 and provides it as an output signal having a frequency F O U T to an output path 150 as well as to the feedback frequency divider 114 in the PLL 130.
  • the loop filter 118 in the synthesizer 100 also filters out jitter, e.g. caused by noise of the charge pump 117, and prevents voltage overshoot.
  • the synthesizer 200 includes a further control loop 230 inside the PLL 130.
  • the further control loop 230 includes a phase detector 201 connected to a further loop filter 203 and a phase rotator 205 connected to the further loop filter 203.
  • the phase rotator 205 is in a path 207 between the VCO 120 and an output path 150 and between the VCO 120 and the feedback frequency divider 114.
  • the VCO 120 and other components of the synthesizer 200 may beneficially be fabricated in the form of an integrated circuit, e.g. on a semiconductor chip using known fabrication technology.
  • the integrated circuit may also include most of the other components of the synthesizer 200.
  • the reference oscillator 102 and the loop filters 118 and 203 are the only components that will normally need to be supplied separately. In other words, all components enclosed by a dashed line 260 shown in FIG. 1 may be fabricated together in the form of an integrated circuit, e.g. a semiconductor chip. In some cases, it may even be possible to include the loop filter 118 and/or the loop filter 203 in the integrated circuit.
