Abstract:
This paper describes a wideband low phase noise frequency synthesizer. It operates in the multi-band, including digital radio mondiale(DRM), digital audio broadcasting(DAB), amplitude modulation(AM)and frequency modulation(FM). In order to cover the signals of the overall frequencies, a novel frequency planning and a new structure are proposed. A wide-band low-phase-noise low-power voltage-control oscillator(VCO)and a high speed, wide band, high frequency division ratio pulse swallow frequency divider with a low power consumption are presented. The monolithic DRM/DAB/AM/FM frequency synthesizer chip is also fabricated in a SMIC’s 0.18-μm CMOS process. The die area is 1 425 μm×795 μm including the test buffer and pads. The measured results show that the VCO operating frequency range is from 2.22 to 3.57 GHz, the measured phase noise of the VCO is 120.22 dBc/Hz at 1 MHz offset; the pulse swallow frequency divider operation frequency is from 0.9 to 3.4 GHz. The phase noise in the phase-locked loop(PLL)is -59.52 dBc/Hz at 10 kHz offset and fits for the demand of the DRM/DAB/AM/FM RF front-end. The proposed frequency synthesizer consumes 47 mW(including test buffer)under a 1.8 V supply.
