Bob Perrin

PDF, PDF HTML, HTML Practical Analog Design

Time for a refresher on op-amps? If so, here's the article for you. Bob covers op-amps from the basics of common op-amp configurations and modeling to the more advanced aspects of instrumentation amplifiers and complex circuit designs.

PDF HTML, HTML Antialiasing Techniques

To get rid of aliasing in an ADC system, you can use linear active filters, switched-capacitor filters, ... You also better know when a filter isn't the answer. So, check out Mike's hints for anticipating as well as solving aliasing problems.

Real-Time PC

Graphical User Interfaces in RTOSs

We can interface with an embedded PC via the Web, but how about a view that doesn't depend on HTML? And, what counts as real time for GUIs, anyway? Ingo has the answers as he gives us a close-up look at X Windows and QNX's Photon.

A New View, Part 1: Virtual Instrumentation

Got a budget limit on test instruments for those one-of-a-kind gadgets? Well, don't spend your money. Instead, do what Fred does -- generate virtual test equipment using National Instruments' LabVIEW.


Don Lancaster

PostScript Flutterwumpers

Pick a Peck of PostScript PICs

The sound of "flutterwumpers" brings on a sort of Alice in Wonderland enchantment that's not unlike the peculiar magic Don Lancaster pulls out of PostScript. Listen in on how to make PostScript move PIC-powered robots.

EMI Gone Technical, Part 4: Transient-Suppression Design Technique

To tie together all his ideas on protecting against EMI and transient threats, Joe presents the protocol he uses when designing for transient protection. These general guidelines help you stop EMI from sneaking through.


Jeff Bachiochi

Rebirth of the Z8, Part 2: Let Your Micro Answer All

Want to see the future? Jeff's project merges a piece of the past (remember your old Magic 8-ball?) with Zilog's new OTP processors. It's crystal clear how easy it is to implement one of these new Z8s.

FPGA Tool Time

It's find to have a low-cost FPGA, but if the tools cost a mint, you're still in trouble. However, Tom's found some bargain basement tools just as far away as your local Internet connection.
