Parasitics & Capacitor Selection, Part 1B: Leakage
Chris Reynolds 2/24/2014 9 comments
Parasitics often play a greater role in determining the suitability of a capacitor for a given application than the actual capacitance value of the part itself. In Part 1b of this series, we'll cover DCL limits, voltage and temperature effects, and takeaways for design and process engineers.

A simple hardware instrument can be a big help when designing circuits for transducer and analog I/O -- if you know what to look for.
Planet Analog 'Ask the Experts' Monthly Technical Sessions
Steve Taranovich 2/10/2014 32 comments
I will be changing a number of things at Planet Analog. One of the first new (but not so new) additions will be to have more tutorial/educational tech blogs. A brand new addition will be the monthly "Ask the experts" session in which we will have a panel of the best experts in the industry for each topic.
Signal Chain Basics #86: Fundamentals of Temp Sensors
Signal Chain Basics 2/10/2014 10 comments
How does a silicon temperature (temp) sensor IC actually measure temperature? Temp sensor ICs are very simple to use and work on very fundamental principles. Taking these principles into account allows a designer to achieve the most accurate result possible.
RFID & NFC Enabling Solutions: a Closer Look
Victor Lorenzo 2/7/2014 83 comments
RFID and NFC are becoming more and more popular every day. As now mature standards, RFID & NFC are also becoming enabling technologies for adding wireless access in smart metering and other applications.
What Can Basic RLC Sensing Tell You?
Analog Angle 2/6/2014 1 comment
We are so comfortable with leading edge, advanced instrumentation and associated measurements that we can easily overlook what fundamentals such as resistance, inductance, and capacitance readings.
Integrated Analog: What’s Missing?
Didier Juges 2/4/2014 3 comments
The analog world is still largely plowing into the micron domain, while digital is at the deep sub-micron level. Yet, there have been several revolutions in analog functionality since the advent of the digital age.
Integrated Analog at the 2014 ISSCC
Doug Grant 2/3/2014 6 comments
When it comes to this month’s ISSCC show, there are plenty of sections dedicated to solving issues with integrated analog technology. Here, our blogger looks at the sessions that offer new insight to difficult problems.
Is Noise Always Unwanted?
Victor Lorenzo 2/3/2014 8 comments
Noise is almost invariably seen as an unwanted signal, but sometimes things can be different. Noise can eventually be the signal of interest.
Analog circuits inherently have some inaccuracies; if these exceed the allowable specification, there are three general strategies to dealing with them.
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
