Design and analysis of a 3.85–5.23 GHz linear-tuning CMOS LC-tank VCO

A low‐phase‐noise and low‐power CMOS colpitts VCO using Gm boosting and capacitance switching techniques

“…According to Reference 5, the dual‐core and wideband VCO with concentric 8‐shaped coils was immune to stray magnetic fields, but its penalty was lower quality factor. A linear LC‐tank VCO using distribution MOS varactor array increased linear‐tuning sensitivity in Reference 6. However, the power consumption of the circuit 6 was twice as high as the proposed VCO in this letter.…”
