Abstract
The invention relates to a radiofrequency oscillator which incorporates: a spin-polarized electric current magnetoresistive device (6), a terminal (18) for controlling the frequency or amplitude of the oscillating signal, a servo loop (34) connected between the output terminal and the control terminal for applying a control signal to the control terminal in order to slave a characteristic of the oscillating signal to a reference value, the servo loop (34) comprising: a sensor (36) of the amplitude of the oscillating signal oscillations, and a comparator (38) capable of generating the control signal according to the measured amplitude and the reference value.
