Abstract: The API techniques used in the fractional-N frequency synthesizer are introduced. The spurious modulation, residual phase error and model of phase error compansation in fractional-N frequency synthesis are analyzed in detail. The method used in the fractional-N frequency synthesizer with API techniques, key points of application and experimental results are provided.

Key words: fractional dividor, API, compensation technique
