Abstract :
We present a new voltage-controlled oscillator structure featuring dual-mode outputs which are mutually locked to octave bands, while consuming only one current branch. The characteristics of coupled LC tanks are analyzed and a structure for realization of a low current dual mode oscillator is presented. A prototype has been fabricated and measured to demonstrate the feasibility of the idea.
