A Novel ROM-based 1.6GHz Frequency Synthesizer in 0.35um CMOS Technology
碩士 === 華梵大學 === 電子工程學系碩士班 === 94 === In this thesis, a novel CMOS fractional-N frequency synthesizer in TSMC 3.3V 2p4m technology is presented. The synthesizer has 84 channels, with a channel spacing of 1 MHz. The chip contains a ROM-based fractional-N frequency divider, a five-ring-interlocked volt...

The synthesizer has 84 channels, with a channel spacing of 1 MHz. The chip contains a ROM-based fractional-N frequency divider, a five-ring-interlocked voltage-control oscillator (VCO), a phase frequency detector (PFD), a charge pump, and the loop filter. The frequency divider improves the divisor sequences generated by the mash delta sigma modulator. The modified sequences are stored in a ROM. The VCO possesses a configuration of five rings interlocked together that has better phase noise performance than a single ring structure. The phase noise and stability issues are discussed in this thesis. Chia-Yu Yao 姚嘉瑜 2006 學位論文 ; thesis 61 zh-TW |
