AB  - This paper presents a diode varactor and MOS varactor voltage control oscillators using 0.25?m CMOS technology, proposed for Ultra Wideband application. The VCOs are designed for 3-5GHz UWB Impulse Radio, The VCO's has 107.6 dBc/Hz and 108.8 dBc/Hz phase noise at 1 MHz offset frequency. The diode varactor VCO has a tuning range of 300 MHz and the MOS varactor VCO has a wider tuning range of 610 MHz which is very difficult to achieve. Their power consumption at the maximum oscillation frequency is 2.26 mW from a 1.2 V voltage source, with 9 dBm output power which is very low compared to the conventional VCO in similar process design. © 2012 IEEE.
