SELF-HEALING CIRCUITS USING STATISTICAL ELEMENT SELECTION by Gokce Keskin Doctor of Philosophy in Electrical and Computer Engineering Carnegie Mellon University Professor Lawrence T. Pileggi, Chair Process variations in advanced CMOS process nodes limit the benefits of scaling for analog designs. In the presence of increasing random intra-die variations, mismatch becomes a significant design ch...

In recent years, steady improvement on both performance and energy efficiency of LSI systems by virtue of the miniaturization of CMOS process has been harder. However, lower power devices are still demanded, especially in growing IoT market. Although near-/sub-threshold voltage operation is one of promising ultra-low-power techniques, there are critical issues on exponential performance degrada...

Introduction of sub-90nm technology has made a profound impact on circuit designs. Thus, it requires understanding of existing design styles for desired energy-efficiency. We compare adder designs in the energy-delay space, implemented with Limited Switch Dynamic Logic (LSDL) and Compound Domino Logic (CD) in a 65nm SOI technology. Evaluation results show that LSDL can provide more than 35% ene...

Today, the use of CMOS technology for the manufacture of electronic ICs has faced many limitations. Many alternatives to CMOS technology are offered and made every day. Quantum-dot cellular automata (QCA) is one of the most widely used. QCA gates and circuits have many advantages including small size, low power consumption and high speed. On the other hand, using special digital gates called re...

Power and cost constraints in the internet-of-things (IoT) extreme-edge TinyML domains, coupled with increasing performance requirements, motivate a trend toward heterogeneous architectures. These designs use energy-efficient application-class host processors to coordinate compute-specialized multicore accelerators, amortizing architectural costs of operating system support external communicati...

1. Introduction The global need for high performance and low power computing continues to be a major driver of the semiconductor industry. In the high performance computing segment, complex projects (such as medical imaging, genomics research and weather prediction) need significant performance increases to fulfill growing expectations. The core computing segment requires performance increases ...

quantum-dot cellular automaton (qca) is a novel nanotechnology with a very different computational method in compared with cmos, whereas placement of electrons in cells indicates digital information. this nanotechnology with specifications such as fast speed, high parallel processing, small area, low power consumption and higher switching frequency becomes a promising candidate for cmos technol...

The key message of this paper is that process variation is not an insurmountable barrier to Moore’s Law, but is simply another challenge to be overcome. This message is illustrated with data from the 45nm process generation where process variation is shown to be at least equivalent to (and in many cases better than) process variation in the 65nmand 90nm-process generations. We begin this paper ...
