Differential Electrically Insulated Magnetoelectric Spin-Orbit Logic Circuits

Abstract

Beyond complementary metal–oxide–semiconductor (CMOS) devices have functionalities different from CMOS transistors, and therefore, the development of novel circuits that leverage their properties is necessary for their practical application to computing. The magnetoelectric spin-orbit (MESO) device has been proposed as one of the promising energy-efficient beyond CMOS device candidates, and several basic circuit blocks have been demonstrated with MESO. In this work, we propose a new differential MESO device that enables differential logic circuit design with better interstage isolation. This improves the output voltage of MESO circuits, provides signal common-mode noise rejection, and eliminates any sneak current path. We demonstrate the functionality of multiple essential logic circuit blocks implemented with MESO devices.
