A quad-core 27-GHz LC oscillator is presented that has a single highQ mode. The suppression of the three unwanted modes removes any mode ambiguity and enhances the Q of the wanted mode. The design is ...

This paper describes a mode-switching quad-core-coupled millimeter-wave (mm-wave) voltage-controlled oscillator (VCO), using a single-center-tapped (SCT) switched inductor for extension of the ...
