www.electronics-eetimes.com/en/Learning-center/ A leading reference resource for electronics engineers, E Times Europe’s White Paper library includes over 600 white papers, application notes, technical articles, books and case studies that can be downloaded free of charge. The latest featured papers are available below. 4-20 mA, Loop Powered, Thermocouple System Using ARM The circuit note describes a complete loop powered thermocouple temperature measurement system. The PWM function of a precision analog microcontroller controls the 4 mA-to-20 mA output current. This circuit provides a low cost solution to temperature monitoring because most of the circuit functionality is integrated into the ADuCM360 (or ADuCM361) precision analog microcontroller. www.electronics-eetimes.com/en/Learning-center/ Managing Electrical Complexity with a Platform Level Approach and Systems Engineering In this competitive and challenging environment, thought-leaders are recommending a shift to systems engineering. Using a systems engineering approach could help OEMs maintain product quality, reduce costs, manage change, and achieve time to market. This paper talks about applying systems engineering principles using the Capital tool suite to address these issues. www.electronics-eetimes.com/en/Learning-center/ Using Next Generation Power Firmware to Simplify Energy Star Compliant Designs Exar’s PowerXR programmable power management system provides a cost effective and easy to change solution for ENERGY STAR rated products both in the USA and worldwide. The ability to configure the power system via an easy to use GUI allows ENERY STAR compliance to be quickly achieved for idle and standby modes. Even as late as 2007, different countries have had different views as to how to address the need for driving manufacturers to design more power efficient products. In order to promote trade a common set of specifications, procedures and labeling have been created by many countries so that consumers can readily identify the efficiency of various products. www.electronics-eetimes.com/en/Learning-center/ UltraCMOS Semiconductor Technology Platforms: A Rapid Advancement of Process & Manufacturing For more than 20 years, Silicon-on-Sapphire (SOS) technology—an advanced form of Silicon-on-Insulator (SOI) processing—has been used in semiconductor manufacturing. Recently, SOS in the form of UltraCMOS technology has been designed into high-volume applications that have made it the technology of choice for several demanding RF applications.

We combine a top-down functional approach, based on early system-level modelling, with a bottom-up performance approach based on transistor level simulations, in an agile development methodology www.electronics-eetimes.com/en/Learning-center/ An Introduction to Rigid-Flex PCB Design Best Practices Designers increasingly face project requirements for densely populated PCBs including pressures to reduce manufacturing times and costs. To meet these requirements, design teams have increasingly turned to 3D rigid-flex circuits to meet their project’s performance and production requirements. Designing for rigid flex presents a number of challenges to electronic and mechanical design teams. This Altium whitepaper lays out some of the golden rules for successful rigid-flex PCB design. www.electronics-eetimes.com/en/Learning-center/ www.electronics-eetimes.com Electronic Engineering Times Europe January 2014 51
