Abstract
Since Internet of Things devices should ideally be self-powered, there is great demand for devices with ultra-low operating voltages that can run on energy harvested from a noisy environment. In this paper, a novel all spin logic (ASL) device with voltage controlled magnetic anisotropy (VCMA) effect amplified by negative capacitance (NC) is proposed for the first time. This novel device can operate at a working voltage as low as 1 mV. A three-step pulse scheme is also proposed. Based on simulations of the VCMA effect and the NC effect coupled with the spin modular approach, the feasibility of the proposed ASL device with a 1-mV working voltage and its immunity to variations in device parameters and supply voltage are analyzed.
