In this paper, an inductor-less, high frequency tuning range and low power CMOS voltage controlled oscillator (VCO) is presented. The VCO can be implemented in 0.18 µm CMOS, with 1.8 V supply voltage. By using a novel structure, a high frequency tuning range, low phase noise and low power consumption VCO, is obtained. In order […]
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 […]
