Abstract |
|
Most signaling process systems need frequency or time reference signals. Oscillators are needed to get the carrying signals for radio wave transmission, however additionally for the most clocks of processors. This paper deals with the analysis and style of CMOS oscillator specifically voltage controlled oscillators (VCOs).Voltage Controlled signal generator is an electronic generator whose output frequency is controlled by a voltage input. VCO is designed with several circuit techniques. Primarily, there are ring oscillator, relaxation oscillator and resonant oscillator. There are various factors which should be considered which designing an oscillator i.e. stability, giant electrical tuning range, gain factor, linearity of frequency verses control voltage and cost. On the premise of that the comparison between CMOS VCOs is represented. |
