主　　题：CMMB PLL frequency synthesizer phase noise sigma-delta modulator 

摘      要：A wide-band frequency synthesizer with low phase noise is *** frequency tuning range is from 474 to 858 MHz which is compatible with U-band CMMB application while the S-band frequency is also included. Three VCOs with selectable sub-band are integrated on chip to cover the target frequency *** PLL is fabricated with 0.35μm SiGe BiCMOS *** measured result shows that the RMS phase error is less than 1°and the reference spur is less than -60 *** proposed PLL consumes 20 mA current from a 2.8 V *** silicon area occupied without PADs is 1.17 mm;.
