Abstract
The present invention provides a spin-transfer torque type injection locking oscillator which improves both power and noise performance by using pair of spin-transfer torque devices. One is optimized for high power and the other is optimized for low noise characteristics. The output signal of the low noise spin-transfer torque device is injected into the high output power spin-transfer torque for phase locking. The present invention has several advantages such as the miniaturization, the high quality and low cost, and the mass production of integrated chips by the nanoscale.
