主 题:LC VCO voltage controlled oscillator phase noise CMOS UWB IMT-advanced
摘 要:This paper presents an LC voltage controlled oscillator(VCO) in a dual-band frequency synthesizer for IMT-advanced and UWB *** switched current source,cross-coupled pair and noise filtering technique are adopted in this VCO design to improve the performance of the phase noise,power consumption,voltage amplitude,and tuning *** order to achieve a wide tuning range,a reconfigurable LC tank with 4 bits switch control is adopted in the core circuit *** size of the entire chip with pad is 1.11 0.98 *** test results show that the current dissipation of the VCO at UWB and IMT-Advanced band is 3 mA and 4.5 mA in a 1.2 V *** tuning range of the designed VCO is 3.86-5.28 GHz and 3.14-3.88 *** phase-noise at 1 MHz frequency offset from a 3.5 GHz and 4.2 GHz carrier is-123 dBc/Hz and-119 dBc/Hz,respectively.
