Abstract:
A frequency synthesizer capable of generating all the 14 sub-band carrier frequencies in 3.1∼10.6GHz band for multi-band OFDM ultra-wideband (MB-OFDM UWB) transceivers is proposed. It is composed of a phase-locked loop (PLL), two single-sideband (SSB) mixers, and two multiplexers (MUXGHs). Switched-cascode architecture with switched LC tanks is adopted in the multiplexers to ensure fast switching. A buffer with series peaking is employed for the output SSB mixer to enlarge its bandwidth. The synthesizer is designed in TSMC 0.18μm CMOS technology. The simulated switching time between each sub-band is approximately 3ns. The current consumption excluding that of the PLL is 25mA under 1.8V power supply. © 2010 IEEE.
