A Wideband Fast Start-Up Multi-Core VCO With Auto-Frequency Control in 0.18 μm CMOS
A 2.8 – 4.6 GHz wideband multi-core VCO with a fast start-up scheme is presented in this brief. The proposed multi-core VCO uses a successive approximation register based auto frequency control (SAR-AFC) loop with the embedded 2/3 Judge to ensure the desired output frequency. To benefit a...
