  • Abstract
    A low phase noise, low spur, DLL-based frequency synthesizer, utilizing a novel charge pump phase comparator and edge combining circuit to reduce the jitter and spur is reported. To prove its feasibility, a 9-time multiplication frequency synthesizer is designed and fabricated in 0.18 μm CMOS technology with an active area of 0.05 mm2. The output exhibits a spur power of -46.17dB below carrier and a phase noise of -107.17 dBc/Hz at 10 kHz offset with a reference frequency of 173 MHz from an RF generator.
