A Power-Optimized CMOS Quadrature VCO with Wide-Tuning Range for UWB Receivers
This paper presents a power-optimized quadrature VCO with wide-tuning range for UWB Receivers. The optimization of power is achieved by both optimum selection of LC tand and the improvement of the conventional VCO. To increase the tuning range, the digital controlled capacitor array is exploited. The circuitry is implemented by the 0.18um RF/mixed signal process. The proposed VCO achieves phase noise of -125dBc/Hz at 1-MHz offset and 34% tuning range while
