2008 International Conference on Intelligent Information Hiding and Multimedia Signal Processing
Wide-Band Low-Noise Quadrature VCO Design
August 15-August 17
ISBN: 978-0-7695-3278-3
A 2.9GHz quadrature VCO designed in a 0.18um CMOS process achieves a very wide tuning range of 77% when the supply voltage equals 1.8V. The phase noise is -120dB/Hz at 1MHz offset for the oscillation frequency of 2GHz, and -104dB/Hz at 1MHz offset for the oscillation frequency of 4GHz. The coupled oscillator architecture is adopted to widen tuning range and to minimum phase noise. Accurate quadrature outputs are maintained throughout the entire frequency range, as needed in all modern transceiver architectures.
