摘要： A demodulator of an FM signal modulated about a carrier frequency with a modulation frequency has an RF oscillator configured to be synchronized, under identical conditions of operation, with oscillations at first and second frequencies used in the FM signal to encode respective pieces of information. The oscillator has a magnetoresistive device; and a low-pass filter connected to an output electrode of the magnetoresistive device to filter an oscillating signal, generated by the oscillator and to a rendering terminal to provide, as a demodulated electrical signal, the filtered signal, the cut-off frequency fc at −3 dB of this filter being strictly lower than the frequency and higher than the modulation frequency.

摘要： A synthesizer includes a second frequency-synthesizing stage comprising a radiofrequency oscillator configured to oscillate at a frequency αfo when it is synchronized with a signal s0(t), where a is a rational number different from one such that αf0=ft. The radiofrequency oscillator has a magnetoresistive device within which there flows a spin-polarized electrical current to generate a signal st(t) oscillating at the frequency ft on an output electrode connected to the rendering terminal. This device is formed by a stack of magnetic and non-magnetic layers, a synchronization terminal for synchronizing the frequency of the oscillating signal st(t) with the frequency of the signal received at the synchronization terminal. The synchronization terminal being connected to the output terminal of the first stage to receive the signal s0(t).
