This fabric update summarizes recent advances for the Nanoscale Application Specific Integrated Circuits (NASICs) nanoscale computing fabric. We provide a brief overview of NASICs, and discuss recent work at all fabric levels. We present advances in device design and optimization including omega gated and junctionless nanowire field effect transistors,(More)
— Several nanoscale-computing fabrics based on novel materials such as semiconductor nanowires, carbon nanotubes, graphene, etc. have been proposed in recent years. However, their integration and interfacing with external CMOS has received only limited attention. In this paper we explore integration challenges for nanoscale fabrics focusing on registration(More)
— Emerging nano-device based architectures are expected to experience high defect rates associated with the manufacturing process. In this paper, we introduce a novel built-in heterogeneous fault-tolerance scheme, which incorporates redundant circuitry into the design to provide fault tolerance. A thorough analysis of the new scheme was carried out for(More)
Reliable and scalable manufacturing of nanofabrics entails significant challenges. Scalable nanomanufacturing approaches that employ the use of lithographic masks in conjunction with nanofabrication based on self-assembly have been proposed. A bottom-up fabrication of nanoelectronic circuits is expected to be subject to various defects and identifying the(More)
—Various fault-tolerance techniques have been proposed in recent years to tolerate the high defect rates expected in emerging nanofabrics with unconventional nano-manufacturing techniques. The proposed techniques include modular redundancy schemes that use majority voters to vote on the '0' or 1' outputs of redundant modules. Novel nanoscale computational(More)
In this project, a multilevel inverter was designed and implemented to operate a stand-alone solar photovoltaic system. The proposed system uses selective harmonics elimination pulse-width modulation (PWM) in the multilevel inverter to convert DC voltage from battery storage to supply AC loads. In the PWM method, the effectiveness of eliminating low-order(More)
While the classical control techniques for three-phase two-level three-leg inverters are based on pulse width modulation or 3-D space vector modulation, this paper presents a Finite Control Set Model Predictive Control (FCS-MPC) strategy for a two-level three-leg voltage source inverter with resistive-inductive load. Model predictive control method chooses(More)
