Design and Analysis of VCO in RF Transceiver

MEI Zhen-fei,CHEN Jun-ning,WU Xiu-long (Institute of Electronic Science and Technology,Anhui University,Hefei 230039,China)  
According to the high data transfer rate and low bit error rate,and the higher demand for each part of the current communication system, a complementary cross-coupled VCO(voltage controlled oscillator) was designed with harmonic filtering resistor to reduce the phase noise and power dissipation.The circuit was simulated using 0.35 μm CMOS technology in Mentor Graphics Eldo-RF environment,the simulation results show that the phase noise of the oscillator can reach-118.4 dBc/Hz@1MHz at 4.0 GHz,1 mA,the power dissipation is only 1.83 mW,and the charactenistic satisfies the current basic requirements of the RF communications systems.
