[Technology Report]
Power-Supply ICs Go Multiphase To Take On 100-A Loads
After a bumpy start, monolithic multiphase pulse-width-modulate (PWM) controllers have made significant strides in cost and performance. They're being rapidly accepted in fast-responding dc-dc converters that power new-generation multigigahertz...  — Ashok Bindra

[Design Application]
"UML Lite" Offers Simple Yet Powerful Tool Set For Even Complex Designs
In recent years, the Unified Modeling Language (UML) has been successfully used to develop many embedded applications, including avionics, automotive, medical, industrial automation, and telecommunications. Its success is due to its simple notation,...  — Bruce Powel Douglass

[Ideas For Design]
High-Q Bandpass Filter Is Well Suited To Current-Mode Signal Processing
Analog signal processing has conventionally been viewed as a voltage-dominated form of design. But voltage-mode processing can restrict the system's dynamic range. There is also a limitation on the input range of signals for linear operation. An...  — Saurav Gupta , et al.

[Ideas For Design]
Interface 20-Bit Sigma-Delta ADCs Through A PC's Parallel Port
In most sigma-delta analog-to-digital converter (ADC) applications, the serial data transfer occurs through a serial port. A microcontroller configures the serial port as required—setting the baud rate and stop/start bits, initializing the serial...  — J. Jayapandian

[Ideas For Design]
Read Temperature With One Digital Output And One Digital Input
Before the MAX6629/30/31/32 series of temperature sensors were available, all digital-output temperature sensors were I2C (alternatively called SMBus) sensors that had to be written to for addressing, before they were read. Prior SPI...  — Jerry Steele

[Editorial]
Just Being New Doesn't Make It Better Technology
From time to time, readers chide me for using a picture in this column of me with a pen and paper in hand. These readers claim that because pen and paper represent old technology, they must be passé. I take exception to that notion. Although I...  — Dave Bursky

What's All This Drilling Stuff, Anyhow?
I had planned on drilling holes in some small strips of wood—pilot holes for brads. But I couldn't find my best small drills. I was annoyed with myself. Then I realized that I didn't have go out and buy a drill bit of exactly the right...  — Bob Pease

[Embedded in Electronic Design]
How Long Until We See The Prototype?
I like hands-on evaluations because they provide a better idea about how well developers can make use of a tool. My background in hardware and software development lets me check out major features and see how hard it is to get a real application...  — William Wong
