Design and Demonstration of MEM Relay-Based Arithmetic and Sequential Circuit Blocks

The Internet of Things (IoT) has become more prevalent in recent years and is an integral part everyday life. Thus, the need for ultralow-power sensors processing units dramatically increased. continuous scaling CMOS transistors resulted severe subthreshold leakage high power density issues. In years, microelectromechanical (MEM) relays have attracted research interests. They are viewed as promising beyond-CMOS candidates due to their nonleaking property abrupt switch ON/OFF characteristics. This article presents design characterization a few core relay-based digital blocks, including adder D-latch. While mechanical movement makes them inherently slower than transistors, we show that scaled 32-bit relay offers 60 times less energy per operation its counterpart 40-nm technology. proposed circuits particularly appealing applications with stringent demand on efficiency moderate performance requirements, such remote sensors, wearable accessories, implantable biomedical devices.
