OCS: Octave Circuit Simulator

OCS was developed during the CoMSON (Coupled Multiscale Simulation and Optimization) project which involved several universities but also several industrial partners. Each of the industrial partners at the time was using its own circuit simulation software and each software had different file formats for circuit netlists. Given the purposes of the project and the composition of the consortium the main design objectives for OCS where

• provide a format for "element evaluators" independent of time-stepping algorithms
• provide a "hierarchical" data structure where elements could be composed themselves of lumped-element networks
• allow coupling of lumped-element networks (0D) and 1D/2D/3D device models
• use an intermediate/interchange file format so that none of the formats in use by the industrial partners would be favoured over the others
• be written in an interpreted language for quick prototyping and easy maintenance
• be Free Software

[Course] Advanced CMOS/FinFET Fabrication

February 6, 2017; Portland, OR, USA

Semiconductor and integrated circuit developments continue to proceed at an incredible pace. For example, today’s microprocessor chips have one thousand times the processing power of those a decade ago. These challenges have been accomplished because of the integrated circuit industry’s ability to track something known as Moore’s Law. Moore’s Law states that an integrated circuit’s processing power will double every two years. This has been accomplished by making devices smaller and smaller. The question looming in everyone’s mind is “How far into the future can this continue?” Advanced CMOS/FinFET Fabrication is a 1-day course that offers detailed instruction on the processing used in a modern integrated circuit, and the processing technologies required to make them. We place special emphasis on current issues related to manufacturing the next generation devices. This course is a must for every manager, engineer and technician working in the semiconductor industry, using semiconductor components or supplying tools to the industry.

Abstract—This work presents an ultra-low power oscillator designed to target different contexts, such as crystal-assisted time keeping, reference oscillator to optimize the always on domain of a microcontroller or wake-up timer. This oscillator enables ultra-low power operation in 180nm CMOS technology with EKV3 compact model; the core oscillator consumes 2.5 nW at room temperature, with a temperature stability of 14 ppm/°C [-40°C - 60°C] and 0.07 %/V supply sensitivity [read more...]
