The demand for ever smaller and portable electronic devices has driven metal oxide semiconductor-based (CMOS) technology to its physical limit with the smallest possible feature sizes. This presents various size-related problems such as high power leakage, low-reliability, and thermal effects, and is a limit on further miniaturization. To enable even smaller electronics, various nanodevices including carbon nanotube transistors, graphene transistors, tunnel transistors and memristors (collectively called post-CMOS devices) are emerging that could replace the traditional and ubiquitous silicon transistor. This book explores these nanoelectronics at the circuit and systems levels including modelling and design approaches and issues. Topics covered include self-healing analog and radio frequency circuits; on-chip gate delay variability measurement in scaled technology node; nanoscale finFET devices for PVT aware SRAM; data stability and write ability enhancement techniques for finFET SRAM circuits; low-leakage techniques for nanoscale CMOS circuits; thermal effects in carbon nanotube VLSI interconnects; lumped electro-thermal modeling and analysis of carbon nanotube interconnects; high-level synthesis of digital integrated circuits in the nanoscale mobile electronics era; SPICEless RTL design optimization of nanoelectronic digital integrated circuits; green on-chip inductors for three-dimensional integrated circuits; 3D network-on-chips; and DNA computing. This book is essential reading for researchers, research-focused industry designers/developers, and advanced students working on next-generation electronic devices and circuits.
