Z Meter on a Chip? Impedance Meter Oscillators
Dennis Feucht 9/30/2013 19 comments
To understand how to fabricate an impedance meter on an IC, Dennis Feucht takes a close look at the oscillator that produces the excitation voltage for measuring the device under test. This is the third of three blogs on the topic.
Take a Walk Into the Wall of Flame
Jason Bowden 9/30/2013 7 comments
As engineers, we all have those occasions when our brain seems to temporarily leave our body. How we deal with the consequences is the key to becoming a better engineer. And awards should be given.
Calibration, Part 2
Aubrey Kagan 9/20/2013 8 comments
Continuing the discussion from Part 1, how do you ensure accuracy? How do you perform the calibration? On what reference is this calibration technique based? How does noise affect calibration?
Design & Fabricate an Extra Low Power MDLL
Brad Albing 9/19/2013 7 comments
For present-day communications devices, you always need an accurate frequency source – and more likely multiple sources. For portable devices, how do you get that and stay within your power budget?
This Little Relay Stayed Home
Peter Zawistowski 9/17/2013 20 comments
Like the switch, the relay is a pretty simple device. Specifying it can be difficult if details are overlooked. Here's a quick summary of some relay types and functions.
Floorplanning for Mixed-Signal Chips
Brian Bailey 9/13/2013 9 comments
When fabricating a new IC, deciding where the various blocks should be located is a complex task. Careful planning is required. Here is an overview of the recommended approach.
Point/Counterpoint: Let's Debate Integration
Analog Angle 9/12/2013 7 comments
Sometimes following a trend is the right way to go, and sometimes it's not; it's an issue that designers and users of analog-centric ICs have been debating since the early days of integration.
Medical Implantable Electronics: Promises & Challenges
Brad Albing 9/11/2013 9 comments
Planet Analog and Integration Nation will have a special live chat Thursday, Sept. 19, at 11:00 a.m. ET (15:00GMT/UTC) on medical implantable electronics. Please join us for a lively discussion of how these devices are changing our world.
We Need Cheap LED Drivers
Brad Albing 9/11/2013 31 comments
There are already LED drivers intended for power-line applications that are triac dimmable. Now, how about devices that are low-cost?
Understanding JESD204B Link Parameters
Jonathan Harris 9/10/2013 10 comments
Understanding the link parameters give us a better understanding of how a link is structured based on ADC and DAC properties. We exaimne the structure of nibbles and words, samples, lanes, and frames.
Calibration, Part 1
Aubrey Kagan 9/9/2013 20 comments
Analog measuring devices should be calibrated to ensure accuracy. How do you perform the calibration? At how many points? And on what is this calibration technique based?
Free Time & Productivity
James Niemann 9/3/2013 31 comments
Does free time take away from time when you would otherwise be productive? Or does having free time enhance your productive time?
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.
