Using Multiple-Input NEMS for Parallel A/D Conversion and Image Processing

The technology advancements in semiconductor process have led to rapid progress in design and fabrication of multiple-input Nano-electro-mechanical relays/switches (NEM relays/NEMS). This work explores the design space of implementing image processing algorithms using a hybrid multiple-input NEMS -- CMOS architecture. Different from the existing the approaches of building logic gates (e.g. INV, AND, OR, NAND, NOR, etc.) as conventional CMOS circuits, using NEMS, this work takes advantages of the electrical and mechanical physical features of the NEM relays to implement image processing algorithms. Simulation results show that the multiple-input NEM relays can be applied for decision-making and compare-select image processing algorithms. Moreover, we show that NEM relays can operate as parallel analog-to-digital converters (ADCs) with advantages of leakage reduction and power efficiency.
