pp: 72-76An Integer-N Frequency Synthesizer Applied to MB-OFDM UWB 5th Band GroupCheng-Chan Tien, Tsung-Mo Tien, and Christina F. Jou doi:10.2529/PIERS060905123732 Downloads: 1620 Abstract:In this paper, we will discuss an integer-N frequency synthesizer operated at 10 GHz around the MB-OFDM UWB system 5th band group with only 1.5 V supply voltage which owns a varying frequency ranging from 9.29 GHz to 10.9 GHz and delivers -5.9 dBm output power. A single NMOS cross-coupled-pairs forms the core circuit of the voltage-controlled oscillator and delivers a -97 dBc/Hz phase noise at 1 MHz from the carrier signal. The frequency settling time is about 25 μs and the whole circuit power consumption is 23.55 mW.References:1. Green, E. R. and S.
