Abstract
The present invention relates to an oscillator arrangement, arranged for providing an oscillator output and phase noise detection and/or control of said oscillator output, the arrangement comprising a mixer () connected to a low-pass filter (). The oscillator arrangement comprises a first oscillator () and a second oscillator (), where the oscillators () are inter-injection locked to each other by means of at least one coupling element (Q) in such a way that the oscillator output is acquired in quadrature automatically. The present invention also relates to a corresponding method.
