Abstract :
In this paper, a first investigation of the use of spintronic based oscillators has been made with very promising results showing a large frequency tuning range (85%), combined with extremely small die size compare to the standard LC VCO (gain factor of 50). The measured output power is -45 dBm, which is two decades higher than published results from spin valves exhibiting similar narrow RF emissions with a dynamic of 120 dBc. Further improvements in the performance of the STO are expected both at the device level (by magnetic multi-layer engineering) and at the system level, through new oscillator and transceiver architectures.
