Dual-Stage Feedback Techniques for Single-Pole Feedback Compensation Vicor This technical paper proposes and studies the effects of a dual-stage compensation technique for achieving greater than 100kHz crossover frequency of a single pole system converting from 48 V to 1.2V.  By placing a separate non-inverting gain stage after the error amplifier, the necessary gain-bandwidth ... Read more USB-Based Thermocouple Temperature Monitor with Cold Junction Compensation ADI This circuit uses the ADuC7060/ADuC7061 precision analog microcontroller in an accurate thermocouple temperature monitoring application. The ADuC7060/ADuC7061 integrates dual 24-bit Σ-Δ ADCs, dual programmable current sources, a 14-bit DAC, and a 1.2 V internal reference, as well as an ARM7 ... Read more TTEthernet Scalable Real-Time Ethernet Platform TTTech Computertechnik TTEthernet – A Powerful Network Solution for All Purposes enables time-triggered communication over Ethernet networks in all application areas. The network provides all necessary mechanisms for applications as diverse as classical web services and time-critical and safety-critical control system in airplanes. ... Read more IGBT Modules: Data Sheet Comparisons and the Pitfalls of such Comparisons Dr. Arendt Wintrich, Semikron Comparing IGBT modules on the basis of data sheets is not as easy is it may seem. This is because IGBT manufacturers have always used different measurement methods for identical parameters. In real applications, this can lead to surprises such as far higher switching losses. This article takes a close ... Read more 3D-IC Testing with the Mentor Graphics Tessent Platform Steve Pateras, Mentor Graphics Three-dimensional stacked integrated circuits (3D-ICs) are composed of multiple stacked die, and are viewed as critical in helping the semiconductor industry keep pace with Moore's Law. Current integration and interconnect methods include wirebond and flip-chip and have been in production for some time. ... Read more Using Tessent Low Power Test to Manage Switching Activity Giri Podichetty, Mentor Graphics Today's advanced integrated circuit (IC) designs are increasing in complexity, with their seemingly endless progression to smaller geometries, ever increasing integration between analog and digital blocks, and diminishing supply voltages. Both this complexity and the need for energy efficiency in portable ... Read more Addressing 32/28-nm IC Implementation Challenges with Talus Vortex and Talus Vortex FX Magma Design Automation This paper describes the technical and business challenges of implementing designs at the 32/28-nm node. Topics include low-power design, crosstalk effects, process variability, and the dramatic increase in the number of operating modes and corners. Also discussed are the related issues regarding engineering ... Read more Smart Engine for Public Key cryptography Barco-Silex The need for security in embedded application is continuously rising. Public Key cryptography is one of the ways to secure data communication. But Public Key processing requires large computation capability. Processors are commonly used to perform complex operations. However, the processing load ... Read more Analog Signal Chain Guide Texas Instruments The Analog Signal Chain Guide offers selection tables and featured product overviews of signal chain devices, which target a wide variety of applications from industrial, medical, communications, audio, consumer and computing. Whether you need faster speed, higher precision, lower power or smaller package ... Read more Power Components Simplify 1kW Power Design Jeff Ham, Vicor Not long ago, designing a 1,000 W power supply for operation on worldwide AC lines was a task for the most experienced power design engineers. Besides dealing with the design of autoranging front-end rectification circuitry and isolated power conversion stages, the designer faced a myriad of other complex ... Read more

READER OFFER

This month Keithley Instruments is giving away two of its Model 2200 power supplies, worth 735 Euros each, for EETimes Europe's readers to win. The Model 2200-20-5: 20V, 5A, 100W on offer is one of five general-purpose programmable DC power supplies recently launched by the company, designed for source measurement instruments for component, module, and device characterization and test applications.

Part of the Series 2200 family, the unit’s voltage output accuracy is specified at 0.03% and its current output accuracy is 0.05%. The supply’s high output (1mV) and measurement (0.1mA) resolution makes it well-suited for characterizing low power circuits and devices in applications such as measuring idle mode and sleep mode currents to confirm devices can meet today’s ever-more-challenging goals for energy efficiency.

And the winners are:

In our previous reader offer, EPC was giving away ten of its EPC9002 development board kits, worth USD 95 each.
Lucky winners include  I. Blythe and C. Hardman from the UK, M. Casartelli and D. Cogliati from Italy, C. Cossio from Spain, W. Milarch from Germany, r. Milewicz from Poland, M. Prascak from Slovakia, A. Raidl from Austria and M. Taslakov from Bulgaria.
All should be receiving their kits soon. Let's wish them some interesting findings with their projects.
