Abstract
An oscillator has a feedback loop with a signal output, a multi-pole resonator, and a gain block. The gain block applies a gain sufficient to generate a stable oscillation signal at the signal output; and the multi-pole resonator is tunable between two or more resonance modes.
Claims31
An oscillator, comprising:
- a feedback loop having a signal output, a multi-pole resonator, and a gain block, wherein, in operation:
- the gain block operates in saturation and applies a gain sufficient to generate a stable oscillation signal at the signal output, the stable oscillation signal being continuously variable;
- the multi-pole resonator selectably operates in two or more resonance modes;
- and
- the two or more resonance modes are exclusively driven by a noise signal in the feedback loop.
2 more elements
A method of operating an oscillator, comprising the steps of:
- providing an oscillator comprising a feedback loop having a signal output, a multi-pole resonator having two or more resonance modes, and a gain block, the two or more resonance modes being exclusively driven by a noise signal in the feedback loop;
- producing a continuously variable signal having a desired oscillation frequency by:
- operating the gain block in saturation and to apply a gain sufficient to generate a stable oscillation signal at the signal output;
- and
- operating the multi-pole resonator in one of the two or more resonance modes.
2 more elements
A method of designing an oscillator, comprising the steps of:
- providing an oscillator comprising a feedback loop having a signal output, a multi-pole resonator, and a gain block, wherein the multi-pole resonator is selected to have two or more resonance modes, and the gain block is selected to be operable in saturation and to generate a stable oscillation signal at the signal output, and wherein the multi-pole resonator is selected as having two or more resonance modes that generate a continuously variable signal having a desired oscillation frequency, the two or more resonance modes being exclusively driven by a noise signal in the feedback loop.
