Abstract
This paper describes a 4.224GHz CMOS charge pump PLL for Mode 1 MB-OFDM UWB hopping carrier generation. It includes a qudrature VCO of which the frequency range is from 3.98GHz to 4.47GHz(@ 0.4 to 1.5 V), a divider, a PFD, a loop filter, a charge pump, and a lock detector. Designed in a 0.18um CMOS technology, the PLL draws 6.6mA from a 1.8V supply. The phase noise of the designed VCO is -133dBc/Hz@3MHz.
