Voltage-controlled oscillator and a method for tuning oscillations

Abstract

Method and systems are provided for voltage-controlling and tuning of oscillators. An oscillator may comprise comprises an oscillator core configured for contributing gain to oscillations generated in the oscillator and a frequency tuning network connected between the oscillator core and a signal source that provides an input signal for creating the oscillations in the oscillator. The frequency tuning network may be configured for tuning frequency of the oscillations, to inhibit amplifying a first capacitance from the oscillator core and to amplify a second capacitance from the frequency tuning network. The frequency of oscillations may be tuned by varying a capacitance, and isolating one or more of noise sources or parasitic capacitances from the tuning network.
