Abstract
An oscillator comprising a first oscillator circuit having a first inductive portion, a plurality of shared switches for selectively connecting a shared oscillator tuning circuit and a second oscillator circuit having a second inductive portion, the plurality of shared switches and the shared oscillator tuning circuit. In some embodiments, when the first oscillator circuit is active, the second oscillator circuit is inactive to allow the sharing of the shared oscillator tuning circuit.

An oscillator comprising:
- a first oscillator circuit having a first inductive portion, a plurality of shared switches for selectively connecting the first inductive portion to a first oscillator tuning circuit having a first oscillator port and second oscillator port;
- and
- a second oscillator circuit having a second inductive portion, the plurality of shared switches and the first oscillator tuning circuit;
- wherein when the first oscillator circuit is active, the second oscillator circuit is inactive to allow the sharing of the first oscillator tuning circuit.
A non-transitory computer readable medium comprising instructions which when executed by a processing device, cause the processing device to generate a digital representation of an oscillator, the oscillator comprising:
- a. a first oscillator circuit having a first inductive portion, a plurality of shared switches for selectively connecting the first inductive portion to a first oscillator tuning circuit having a first oscillator port and second oscillator port;
- and
- b. a second oscillator circuit having a second inductive portion, the plurality of shared switches and the first oscillator tuning circuit;
- wherein when the first oscillator circuit is active, the second oscillator circuit is inactive to allow the sharing of the first oscillator tuning circuit.
