Abstract :
A 14-band frequency synthesizer for MB-OFDM UWB using an inductor-less design methodology is presented. It is capable of frequency switching across the entire UWB band in approximately 2 nS, and the phase noise is less than -114 dBc/Hz at 1 MHz offset. Implemented in a 0.13 ¿m CMOS technology, the synthesizer dissipates 135 mW from a 1.2 V supply, and occupies only 1.3 mm2 of silicon area.
