ABSTRACT:
Oscillator circuits for reducing phase noise are described in this disclosure. In one embodiment, an oscillator circuit includes a pair of cross-coupled transistors, including a first transistor and a second transistor, a first inductor in communication with a control terminal of the first transistor and an output terminal of the second transistor, a second inductor in communication with a control terminal of the second transistor and an output terminal of the first transistor, and a tank circuit in communication with the first inductor and the second inductor, where the tank circuit comprises a tank inductor and a variable capacitor.
