Method and apparatus of synchronizing oscillators
A circuit includes a first oscillator and a second oscillator. The first oscillator includes an inductive device, a capacitive device, and an active feedback device configured to output a first output signal having a predetermined frequency according to electrical characteristics of the inductive device of the first oscillator and electrical characteristics of the capacitive device of the first oscillator. The second oscillator includes an inductive device, a capacitive device, and an active feedback device configured to output a second output signal having the predetermined frequency according to electrical characteristics of the inductive device of the second oscillator and electrical characteristics of the capacitive device of the second oscillator. The inductive device of the first oscillator and the inductive device of the second oscillator are magnetically coupled.
