Interfacing to ADCs: Power Supplies, Part 5
Jonathan Harris 10/31/2014 2 comments
Previously in this blog series we looked at using a DC/DC converter (switching regulator) in combination with an LDO to drive the power supply inputs to an ADC. What we found was that using the DC/DC converter to step down the input voltage for the LDO was a much more efficient way to drive the power supply inputs to an ADC.
ASSNs: The Proliferation of Sensor Fusion
Marcellino Gemelli 10/30/2014 4 comments
The growing wearable, smart home, and IoT design communities would like to reliably detect, interpret, and understand their products’ motion to captivate users in novel ways.
EMI Noise, Part 2: Don’t Be the Victim
Edgardo Menendez 10/28/2014 19 comments
There is always a source, a path, and a victim when it comes to electromagnetic interference (EMI) and other types of electrical noise. This post focuses on the victim and what you can do to avoid becoming one.
What Competes With Ultracapacitors?
Mike Everett 10/24/2014 27 comments
Ultracapacitor manufacturers that have commercialized the technology find themselves in a constant competitive environment in which consumers weigh the pros and cons of various technologies to determine which one best suits their applications.
Designing SAR ADC Anti-Aliasing Filters
Signal Chain Basics 10/22/2014 6 comments
One of the most challenging aspects in optimizing the performance of a successive-approximation-register analog-to-digital converter (SAR ADC) is the design of the anti-aliasing filter (AAF).
Analog or Digital?

You should be pretty warmed up for "Ask The Experts" by now. Here’s the last of those three conundra. It’s the one that usually provokes the greatest debate.
Narrow or Broad?

What’s getting in the way? Are you trying to filter something out, or filter something in?
Time or Frequency?

This is the first in a rapid-fire sequence of mini-blogs to get your brain cells warmed up for the Ask The Experts session on filter design on October 22.
ADC Input Ranging
Dennis Feucht 10/7/2014 6 comments
The input range of a single-supply ADC can be extended with three resistors and some design formulas.
Smart Cities: The Future of Urban Areas, Part 3
Paolo Scalisi 10/7/2014 8 comments
The communication infrastructure of future smart cities can be used for connecting all the smart systems that are able to manage the electric power in an automated mode, making it possible to increase the energy saving and the safety of big urban areas.
These days, I often code design equations for filter circuits directly into sequences of Excel cells
The introduction of the solar boat is necessary to preserve our planet, which is mainly covered by water; the autonomous drive option is a pleasant alternative
Leading up to APEC have been a slew of new introductions by various suppliers. I wanted to highlight some of that here on Planet Analog for your information
Could a 16-bit SAR converter application reach a dynamic range of 125 dB at 600 kSPS?
My ‘gut feel’ as an Electronics Engineer tells me that the need for more adequate and intensive pilot training is a strong possibility
