MAGNETORESISTIVE RADIOFREQUENCY OSCILLATOR AND METHOD FOR GENERATING AN OSCILLATING SIGNAL
摘要
The invention relates to a radiofrequency oscillator which incorporates: a spin-polarized electric current magnetoresistive device (6) for generating an oscillating signal at an oscillation frequency on an output terminal (10), and a terminal (18) for controlling the frequency or amplitude of the oscillating signal, and a feedback loop (44) comprising an amplifier (46) provided with: an input connected to the output terminal (10) of the magnetoresistive device (6) so as to amplify the portion of an oscillating signal detected at the output terminal, and an output connected to the control terminal (18) so as to inject onto said control terminal the amplified portion of the oscillating signal which is phase-related to the oscillating signal generated at the output terminal.
