Σ-Δ modulation analysis and optimization in fractional-N frequency synthesizer
Analyzed the impaction of Σ-Δ modulation on Σ-Δ frequency synthesizer′s phase noise and spurs, and optimized Σ-Δ modulator to improve the performance of Σ-Δ frequency synthesizer. The Σ-Δ modulator′s order, working frequency, quantization bits, and the bandwidth of frequency synthesizer were analyze...
