A spurs reduction fractional-N frequency divider with a frequency range which is 3.5 times larger than that of a conventional fractional-N divider is presented in this paper. A 1.2-GHz quadrature voltage-controlled oscillator (VCO) is designed as the input source of the frequency divider. The circui...
