Abstract
The design of a Fractional-N Frequency Synthesizer in CMOS 180-nm that operates in GHz range is discussed. The proposed frequency synthesizer is realized using a phase-locked loop with phase frequency detector (PFD), charge pump, loop filter, voltage controlled oscillator (VCO), and a programmable frequency divider. The characteristics of the PFD are extremely linear as one of the input frequencies is modulated. The frequency divider deigned is a programmable one as it can generate noninteger division ratios unlike an integer PLL.
