A 3-10 GHz, 14 Bands CMOS Frequency Synthesizer With Spurs Reduction for MB-OFDM UWB System

This paper presents the design of a 14 bands CMOS frequency synthesizer with spurs reduction for MB-OFDM UWB system. Based on a single phase-locked loop and two-stage frequency mixing architecture, it alleviates harmonics mixing and frequency pulling to diminish spurs generation. Also, only divide-b...
