Whole Larger Than the Sum of its Parts

June 7, 2004 by Staff
The electronics industry has changed a lot over the last two or three years. Most of the change has centered around cost cutting, as manufacturers struggled to improve their bottom lines, and in some cases to merely survive.

Implementation Strategies for USB Circuit Protection

June 7, 2004 by Staff
Figure 1. Circuit protection and power switching requirements for USB.{toggle author}The USB specification requires current limiting and/or power switching for USB power management, and references resettable polymeric positive temperature coefficient (PPTC) devices and solid-state switches as acceptable methods for overcurrent protection. Resettable current limiting in a fault condition helps prevent circuit damage and associated system failure, and helps the system meet UL safety standards.

Figure 1: The incandescent backlighting used for the power output meters in the model MC602 power amplifier (top) caused a blue tint around the edges that became progressively more washed out toward the center. In its newer model MC501, the use of fibre optic panel backlighting resulted in a perfectly uniform, brilliant blue.{toggle author}When it comes to top-of-the-line audio components, no company raises the bar as high as McIntosh Laboratory Inc. does.

Quasi-Resonant, Zero-Current Switching DC/DC Converters

June 7, 2004 by Staff
Figure 1. Diagram of a quasi-resonant, zero-current switching DC/DC converter.{toggle author}Switching converters were introduced in the 1960s to achieve the reductions in size and weight promised by higher than line frequency operation. Initial products had switching frequencies of 20 - 30 kHz. By the late 1970s, with the advent of component improvements such as high-speed transistors, frequencies over 100 kHz were being achieved. Unfortunately, switching-related losses, which also increased with frequency, were becoming prohibitively high. Against this backdrop, the quasi-resonant, zero-current switching (ZCS) DC/DC converter was introduced with switching frequencies of 1 MHz, overcoming the frequency-related loss barrier. Each switch cycle delivers a quantized packet of energy to the converter output, with each switch turn-on and turn-off occurring at zero current, resulting in switch losses related only to current conduction, independent of frequency.

Industry Leaders Gather to Discuss RFID Standards, Cost

June 7, 2004 by Staff
MARKHAM, Ont. -? Industry leaders gathered here in April for Canada’s first radio frequency identification (RFID) conference, in an effort to clarify some of the technical issues and business concerns surrounding the adoption of a technology some believe will have an impact similar to that of the integrated circuit.Organized and hosted by RFID distributor and system integrator R. Moroz Ltd. of Markham, Ont. the two-day event attracted over 250 delegates from retail, banking, manufacturing, and supply chain sectors across the country. RFID is the fastest growing part of R. Moroz’s business, says company president, Bob Moroz. "Last year the RFID side experienced 400 per cent growth, and we forecast two to 300 per cent growth this year," Moroz said.
