There is a growing demand for Systems-on-Chip, integrating microprocessors, on-chip memories, data converters and a variety of sensors, which are capable of reliable operation at high temperatures. For instance, modern aircraft industry demands microcontro ...

This paper proposes an unconventional image acquisition scheme for machine vision applications, based on detecting ratios of illumination (pixel) intensities. Detecting relative ratios enables capturing the scene features and patterns almost independently ...

Journal article A sub-mW pulse-based 5-bit flash ADC with a time-domain fully-digital reference ladder: A Katic, Nikola; Cojbasic, Radisav; Schmid, Alexandre; Leblebici, Yusuf Published in: Microelectronics Journal (ISSN: 0026-2692), vol. 46, num. 12, ...

In this paper, we analyze the 6T SRAM cell failures caused by temperature and supply voltage variations, and we explore the design of robust SRAM cells for high temperature operation. This integral SRAM reliability study is performed using 180nm SOI CMOS p ...

PowerPC Architecture microcontrollers are commonly used in embedded applications. In this work we present FireBird, the first PowerPC based SoC for reliable operation beyond 200C. It is a significant challenge to design SoCs for reliable operation at high ...
