ABSTRACT:
Disclosed is a push-push voltage controlled oscillator which obtains output signals having a frequency two times the fundamental resonance frequency of an LC resonator with differential signals having the same amplitude and opposite phases, creating the advantage of high frequency differential outputs which are obtained using such a voltage controlled oscillator, and thus reducing current consumption.
