The Nature of PCB Losses -- Part 2
News & Analysis  
2/26/2003   Post a comment
This is the time when even experienced digital designers and system engineers need to go back to book and application notes, says signal integrity guru Mike Grabois. In this conclusion to his tutorial on transmission line losses, Mike looks at Inter Symbol Interference and other line losses -- as well as equalization, pre-distortion and other compensation techniques.
Bootstrap power supply permits amplifier output to touch ground
News & Analysis  
2/24/2003   Post a comment
Many single supply powered applications require amplifier output swings within millivolt or even sub-millivolt levels of ground. Amplifier output saturation limitations normally preclude such operation. From the February Planet Analog magazine folio, this famous applications guru offers tips for approaching ground -- without getting stuck there.

The new signal data rates have changed the interface arena completely. The IC manufacturers and tool makers have come up with a number of methods that may save you money and extend life of old components and materials. This is the time when even experienced digital designers and system engineers need to go back to book and application notes, says one our favorite contributors, signal integrity guru Mike Grabois.
Active cooling techniques drive PC thermal management
News & Analysis  
2/19/2003   Post a comment
Miniaturization and portability trends in combination with increasing performance are contributing to the well know problem of heat concentration and dissipation in modern electronic appliances. From the February issue of PA magazine, a Fairchild scientist explores the prospects for active cooling.
How many bits do you need - Part 2
News & Analysis  
2/13/2003   Post a comment
Digital audio systems use finite precision in representing signals and coefficients and in performing arithmetic operations. Consequently, audio system performance is determined by the precision that is used throughout the system. This part of David Zaucha's paper looks at implementation landmines.
Your vending machine can talk thanks to a 5 embedded modem

It's not just coke and Mars bars. Vending machines sell Kodak cameras, CD records, eyeglasses and books - a $56.8 billion market, according to Vending Times magazine. Of this 2000 total, some $39.3 billion was in what the vending industry calls the "four Cs" (candy, coffee, cold drinks, and cigarettes). Wouldn't it be interesting, engineers speculate, if the vending machine could call you up every time it needs to be refreshed. The cost of this add-on, a Cypress Microsystems applications enginee

A system test bus ties together many the products of many manufacturers - JTAG programmable FPGA's, Emulators, ICs with JTAG features, as well as ATPG hardware and software. It enables capabilities like interconnect test, flash programming, emulation, in-system-programming to be accessed at-speed. National Semiconductor's app note suggest how BIST, IEEE P1149.6 (AC Extest), and the IEEE 1149.4 mixed signal test set can all be accessed from a five-wire bus.
How many bits do you need? A discussion of precision for digital audio filters*
News & Analysis  
2/5/2003   Post a comment
Unlike conventional analog systems, in which signals can vary between minimum and maximum values in continuous time, digital audio systems use finite precision in representing signals and coefficients and in performing arithmetic operations. Consequently, audio system performance is determined by the precision that is used throughout the system. This TI presentation discusses the fixed point arithmetic hat influence the performance of Infinite Impulse Response filters in high end audio applicat

To say that Andy Weir's The Martian is an exploration of math, Mars, and feces is a slight simplification. I doubt that the author would have any complaints, though.
