Go ASIC for Analog?
Analog Angle 7/20/2016 2 comments
Analog ASICs offer an alternative that deserves serious consideration, despite the huge number of excellent, off-the-shelf analog ICs.
NASA Juno electronics study Jupiter: Gravity Science Experiment
Steve Taranovich 7/19/2016 Post a comment
The Juno spacecraft now orbiting Jupiter has a suite of science instruments which will investigate the existence of a possible solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras
Short notes about lightning: Part 1
Victor Lorenzo 7/18/2016 3 comments
For engineers and technicians, the event of changing occupation tends to come associated with the challenge of diving into new knowledge areas. Entering into the lightning research and protection world is one remarkable example.
Virtual Eval Through the Eyes of an ADC, Part 2
Jonathan Harris 7/15/2016 Post a comment
Now that we’ve had a chance to learn a bit about the tool we will take a look at using Virtual Eval to predict the performance of the AD9680-500 which has integrated digital downconverters (DDCs) and will compare simulated data to measured data.
Common-Base Bypassing and How It Affects CB Frequency Response
Dennis Feucht 7/8/2016 3 comments
The common-base (CB) BJT configuration is the second stage of cascode amplifiers. It is useful as a voltage translator to the high side of an amplifier with a large voltage range. This article addresses the question of how the RB, CB combination at the base node affects the frequency response.
Active Signal Characterization
Steven LeBoeuf, Ph.D. 7/8/2016 1 comment
The accuracy of biometric wearables continues to get a great deal of attention, particularly related to the accuracy of optical heart rate monitors in consumer wearable devices today. There are many aspects to answering that question, but this post will focus on one of the most important aspects known as “active signal characterization”.

You think that rectification of a signal for power is a trivial matter. Beware, some people think they know, but what they know is dangerous. And that’s without hidden gotchas.
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.
