Win one of two general purpose programmable power supplies delivering up to 100W February 01, 2012 Win one of two general purpose programmable power supplies delivering up to 100W 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 ... Read more Characterizing a linear voltage regulator’s DC performance January 30, 2012 Characterizing a linear voltage regulator’s DC performance Linear voltage regulators (LVRs) are essential elements of power management systems. They provide the constant voltage rails required by any electronic circuit designed to operate at specific DC levels. A properly designed voltage regulator will maintain the specified output voltage continuously, regardless ... Read more Visible and invisible semiconductor light for tomorrow’s TV January 27, 2012 Visible and invisible semiconductor light for tomorrow’s TV When 3D TV started in the 1980s, glasses with differently coloured lenses (red and green) were required to experience the 3D effect. 3D glasses are still with us today but the images have become sharper and more realistic. Today’s glasses communicate with TV sets via infrared light, which is produced ... Read more Testing modern MIMO Wi-Fi and LTE radios January 25, 2012 Testing modern MIMO Wi-Fi and LTE radios Modern radio technologies such as the IEEE 802.11 and 3GPP (3rd generation partnership project) LTE (long term evolution) rely on MIMO (multiple input multiple output) techniques to increase the radio transmission range and speed. MIMO algorithms use multiple synchronized radios (up to 4 for 802.11n ... Read more Test solution and requirements for CDWM January 23, 2012 Test solution and requirements for CDWM WDM is a technology that combines multiple wavelengths on a single mode fibre to increase bandwidth capacity in a network. It can be classified either as Coarse WDM or Dense WDM; Coarse WDM is cheaper, because the channel spacing (spacing between the wavelengths) is large, but has limited scalability ... Read more Geo-location could bring new security risks January 20, 2012 Geo-location could bring new security risks Commenting on the Information Commissioner’s Office (ICO)’s call for a rethink on location privacy, Cryptzone says that geo-location tagging security issues are likely to be a major issue in 2012 and that many users of smartphones are unaware of the potentially serious security consequences of their ... Read more The move to 3D die stacks drives interconnect consortia January 18, 2012 The move to 3D die stacks drives interconnect consortia Chip design, test and manufacturing technology are being driven by the increasing capability to stacks die on top of each other to build multicore 3D systems. New networking protocols are being combined with manufacturing techniques such as silicon interposers to connect the stacked die with silicon ... Read more Expanding synthesis-based test for higher quality and lower cost January 17, 2012 Expanding synthesis-based test for higher quality and lower cost Increasingly, design teams are looking for productivity benefits from their test activities throughout the entire design flow, from test integration through to yield analysis. Integrating that test technology is enabling designers to achieve optimal quality of results (QoR) and eliminate time-consuming ... Read more Integrated sensor nodes with GSM modems: simplifying the task of wireless data acquisition January 02, 2012 Integrated sensor nodes with GSM modems: simplifying the task of wireless data acquisition A sensor network typically consists of a number of sensor nodes which each acquire signals from a sensor or multiple sensors and a system to transmit and process the data acquired from sensors. The sensor nodes can communicate the data within one another or to a centralized location over a wired or wireless ... Read more Win one of ten EPC9002 development boards for your power applications January 02, 2012 Win one of ten EPC9002 development boards for your power applications This month, EPC is giving away ten of its EPC9002 development board kits, worth USD 95 each. Rated at 100V maximum for a maximum output current of 10A, the half bridge assembly features on-board gate drives with the EPC2001 enhancement mode (eGaN) field effect transistor. Measuring 51x38mm, the board ... 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.
