Abstract

Sub-harmonic injection locking is employed to generate the fast-hopping carriers required in UWB systems for WiMedia . A very small area 90-nm CMOS prototype synthesizes the frequencies of band group #6 with a hop time shorter than 4 ns . It occupies 0.074 mm² and draws 30 mA from a 1.2 V supply. Phase noise at 8.71 GHz is -112 dBc/Hz at 1 MHz offset. The design is supported by a thorough analysis that emphasizes the tradeoffs in the parameters of the proposed system.
