Abstract
A VCO is configured in a wide-bandwidth voltage-locked feedback loop that suppresses the VCO phase-noise. By configuring this architecture in a PLL, low phase-noise frequency synthesis is possible using integrated VCOs. The proposed architecture is designed in a 0.8 μm BiCMOS technology and achieves up to 20 dB reduction in the integrated VCO phase-noise
