A complimentary topology is used incorporating TSMC 0.18 mm process to design a CMOS VCO with the center frequency of 5.4 GHz. Simulation results showed tuning range of 13%. The phase noise at 1 MHz offset was measured to be -118.7 dBc/Hz. The VCO core power consumption was 3.3 mW when the power supply voltage […]
This paper presents a wide tuning range, and low noise voltage controlled oscillator (VCO) based on cross-coupled and colpitts structures. The advantages of this work provide a low-phase noise and robust start-up condition, leading to minimized the dc power. In addition, a new structure of capacitor bank is used in this structure to achieve a […]
