Abstract :
A 0.3 mm2 fractional-N synthesizer covering the frequency range from 90 to 770 MHz needed for a digital TV tuner is presented. The synthesizer achieves the specifications of the ISDB-T/Tsb/Tmm standards while maintaining low spurious signals and small area by combining an FIR filtering technique and a circulating register. The phase noise at 1 MHz offset is -119 dBc/Hz. The worst spurious signals are below -61.2 dBc.
