A VCO for multi-standard transceiver should operate in wide-tuning range, while providing low-phase noise quadrature outputs with low power consumption. In this paper, a multi-standard CMOS LC QVCO is designed utilizing reconfigurable LC tank and low power low phase noise quadrature generation method. Designed in 0.18 µm CMOS technology, the VCO achieved very wide tuning characteristics in two separate bands with low power consumption.
