Abstract
A circuit for a single differential-inductor oscillator with common-mode resonance may include a tank circuit formed by coupling a first inductor with a pair of first capacitors; a cross-coupled transistor pair coupled to the tank circuit; and one or more second capacitors coupled to the tank circuit and the cross-coupled transistors. The single differential-inductor oscillator may be configured such that a common mode (CM) resonance frequency (FCM) associated with the single differential-inductor oscillator is at twice a differential resonance frequency (FD) associated with the single differential-inductor oscillator.
