26.2 A 0.08mm2 25.5-to-29.9GHz Multi-Resonant-RLCM-Tank VCO Using a Single-Turn Multi-Tap Inductor and CM-Only Capacitors Achieving 191.6dBc/Hz FoM and 130kHz 1/f3 PN Corner

VCO designs have evolved from single-resonant LC-tank VCOs to the recent multiresonant RLCM (Resistor-Inductor-Capacitor-Mutual-inductance) tank VCOs that allow reshaping of VCO phase-noise (PN) ...
