Where Art Thou Analog IP?
Brian Bailey 4/22/2013 9 comments
Analog IP is available, though certainly not to the extent that digital IP is. Designers have fewer choices regarding multiple sources of the IP they need.
Design Margins in Analog & Digital
William Murray 4/19/2013 16 comments
Design margin can sometimes be a vague concept. It's best to analyze a design carefully and sometimes you must be especially cautious with systems where safety is paramount.
How the Analog Challenge Has Changed
Analog Angle 4/16/2013 2 comments
Today's analog designs are easier than those of the past, due to greatly improved and more highly integrated components; now the design focus is on system-level issues of overall performance meeting power, cost, and time-to-market objectives.
Getting Over My New Integration Fears
Analog Angle 4/12/2013 7 comments
For someone who "grew up" on integration via increased hardware functionality, it takes some time to get used to integration done by applications software tying ICs together.
Why Do We Need SystemC-AMS?
Brian Bailey 4/12/2013 9 comments
Modeling of mixed signal circuits/devices can be done with SystemC-AMS 2.0. Does it offer anything that you can't get elsewhere?
Next Christmas: A Drone Under (or Above) Every Tree
Jack Shandle 4/9/2013 19 comments
Kids today are not satisfied with the GI Joe class of toys. When the Christmas marketing season rolls around this year, low-cost, high-volume drones may top the average 10-year-old's shopping list thanks in part to mixed-signal ICs.
AEA's Ribbon Microphones & Linear Systems' JFETs
Tim McCune 4/5/2013 8 comments
The recording industry favors ribbon microphones for capturing the subtle nuances of classical music for film scores and stand-alone recordings. Ribbon microphones have special requirements for their preamplifiers; audiophiles are very particular regarding the details.
DSL Line Drivers Throw a Party
Barry Harvey 4/5/2013 2 comments
Just as stated in the corollaries to Murphy's Law, self-starting oscillators don't oscillate and very wideband amplifiers do oscillate. Finding and stopping that amplifier oscillation requires some clever techniques and smart sleuthing.
Lessons I Learned From Jerry Fishman
Doug Grant 4/4/2013 Post a comment
Bill Schweber recently posted his remembrances of Analog Devices CEO Jerry Fishman, who passed away suddenly last week. Let me add my own memories and what I learned from Jerry in my 30+ years at that company.
ADC Guide, Part 14: Impedance Matching
Sachin Gupta & Akshay Phatak 4/1/2013 14 comments
In this installment, we’ll see how to design an interfacing circuit for a given signal source to match the output impedance of the source to the input impedance of the ADC. This process is referred as impedance matching.
Removing the vuvuzela narrow-band noise was presenting challenges to broadcast engineers
This article discusses how using a single synchronous buck controller can output the most common voltage rails, and accommodate a wide range of operating input voltages from 3V to 40V, and at a reasonable BOM cost.
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
