A GHz spintronic-based RF oscillator

Wireless devices are usually based on single-frequency RF oscillators (one per band). The state-of-the-art for current technology is a combination of stand-alone high-quality, low-frequency quartz crystals resonators and integrated high-frequency, low-quality LC tank-based phase-locked loops. However, this approach now faces severe limitations in terms of integration due to CMOS scaling, power consumption, and multiple standard requirements.
