This session presents recent advances in voltage-controlled oscillator (VCO) design, covering innovations across sub-THz, mm-wave, and microwave frequency bands. The first paper introduces a 60GHz coupled standing-wave-oscillator LO distribution network, enabling a 240GHz 2D phased array with area efficiency and robust performance. The second paper discusses a compact 190GHz push-push Colpitts VCO in 130nm BiCMOS, demonstrating high DC-to-RF efficiency and substantial output power. The third paper explores an image-reused phase-tuning quadrature VCO (QVCO), achieving a high figure-of-merit (FoM) through an innovative tuning technique at mm-wave frequencies. Finally, a 13.8–16.2GHz series-tank-assisted transformer-based oscillator is presented, offering excellent supply pushing characteristics and a competitive phase noise profile. These contributions highlight key innovations in VCO design across a wide range of frequencies, supporting advances in next-generation communication, radar, and sensing applications.
