摘要：
We present a Dual Pillar Spin Torque Nano Oscillator (DP-STNO) suitable for energy efficient information processing. The proposed DP-STNO consists of a low resistance Giant Magneto-Resistance path that allows ultra-low voltage biasing of the oscillating ferromagnetic-free-layer, and a high resistance Tunneling Magneto-Resistance path that provides amplified RF-signal and facilitates easy sensing mechanism. The free-layers of multiple DP-STNOs can be coupled through dipolar-fields to accomplish complex signal processing tasks, like edge-extraction from an image, with high energy efficiency.
