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.

Abstract: Methods and systems are provided for generating balanced oscillations in oscillators. An oscillator comprises a resonator input configured to receive, from an electro-mechanical resonator, a resonator signal; and an oscillator core comprising a first and a second complementary inverters forming a first loop and a second loop with the resonator input, respectively. The inverters are programmable to contribute to the resonator signal a first gain or a second gain to generate balanced oscillations in the oscillator, with the first gain being less than an upper threshold gain required to generate parasitic-mode oscillations when starting balanced oscillations, and the second gain being equal to or greater than a lower threshold, gain required to generate resonator-mode oscillations. Each inverter is configured to regulate gain contributed by the inventor based on regulating amount of power received to control the gain.
