Abstract
An method of integrating an oscillator includes incorporating a main inductor and a main capacitor for establishing an oscillation; incorporating two cross-coupling NMOST and two cross-coupling PMOST for sustaining the oscillation; incorporating a first auxiliary inductor and a first auxiliary capacitor for suppressing a noise of the two cross-coupling NMOST; incorporating a second auxiliary inductor and a second auxiliary capacitor for suppressing a noise of the two cross-coupling PMOST; laying out the main inductor symmetrically with respect to a plane of symmetry; laying out the first auxiliary inductor as a parallel connection of two halves that are inside the main inductor and symmetrical with respect to the plane of symmetry; and laying out the second auxiliary inductor as a parallel connection of two halves that are inside the main inductor in a close proximity to the first auxiliary inductor and symmetrical with respect to the plane of symmetry.
