Abstract :
This paper describes a frequency synthesizer for DRM/DAB/AM/FM application using 0.18μm CMOS process. The frequency synthesizer operates in the multi-band, including DRM, DAB, AM, and FM. To cover the overall frequencies of them, a novel frequency planning and a new structure are proposed. The monolithic DRM/DAB frequency synthesizer chip is also fabricated in a SMIC´s 0.18 μm CMOS process. The die area is 1425 μm×795 μm (include test buffer and pads). The measured results show that phase noise in PLL loop is -59.52dBc/Hz at 10 kHz offset, the measured phase errors of LO quadrature signals is less than 3°. The proposal frequency synthesizer consume 47 mW (include test buffer) under a 1.8 V supply.
