A programmable frequency divider for fractional-N frequency synthesizers is presented. The input frequency range is from DC to 17GHz for divider ratios from 16 to 255. We show by analysis and time-domain simulations that the quantization noise folding in a fractional-N PLL can be reduced tremendously, if a prescaler between VCO and programmable divider can be avoided by using this high-speed divider...
We present an integrated frequency synthesizer which is able to provide in-phase/quadrature phase signal over the frequency bands 0.6-4.6 GHz, 5-7 GHz, 10-14 GHz, and in-phase signal over 20-28 GHz for software-defined radio applications. An integrated voltage-controlled oscillator (VCO) with 34% tuning range and a set of high-speed dividers are used to accomplish all the frequencies. To achieve a...
