Abstract
A frequency synthesizer includes: a first oscillator () controlled by a first control device, the first oscillator having a high quality factor that is greater than 300 and produces a first clock signal () RF having a fixed frequency, the first control device () controlling the frequency of the first controlled oscillator () on the basis of a first reference frequency; a second oscillator () controlled by a second control device and producing a second clock signal (); the second control device () controlling the frequency of the second controlled oscillator () on the basis of a second reference frequency; and an integer frequency divider () dividing the frequency of the second clock signal () by a variable integer factor Nand producing a third clock signal (), the frequency of which is continuously variable by modifying the factor Nand the control of the second oscillator.
