Abstract
A voltage-controlled oscillator comprising a LC tank circuit coupled to a pair of transistors and crossed-coupled to a pair of emitter follower transistors each transistor having a collector, an emitter and a base, the voltage controlled oscillator being characterized in that a supply voltage applied to the collectors of the emitter follower transistors is substantially different from a supply voltage applied to the bases of the emitter follower transistors.
