Interleaving Spurs: Bandwidth Mismatches
Jonathan Harris 8/29/2013 9 comments
Building from our previous discussion of timing mismatch, we now look at bandwidth mismatch and compare the interleaving problems caused. Also, a summary of the problems is shown.
NRE Costs & Analog Integration
Brad Albing 8/29/2013 10 comments
While you're waiting for IC manufacturers to build the complex parts you want, consider their cost. Then wait a little longer – or consider an important alternative.

Running an analog circuit simulation requires detailed knowledge and representation of the supply buses (ignore at your own peril).
I Like 'Scopes
Barry Harvey 8/26/2013 14 comments
There are analog 'scopes and digital 'scopes. There are good 'scopes and bad 'scopes. There are several manufacturers. How do these categories intertwine?

How do you make a true RMS measurement of a complex (non-sinusoidal) waveform? There are various techniques.
Interleaving Spurs: Timing Mismatches
Jonathan Harris 8/21/2013 3 comments
Building from our previous discussion of gain mismatch, we now look at timing mismatch and compare the interleaving problems caused. We note specifically the similarities with the artifacts created compared to gain mismatches.
It's All 4-to-1 Design
Vincent Biancomano 8/19/2013 8 comments
In design engineering, certain rule-of-thumb ratios crop up regularly. A common one is the 4:1 ratio.
The Elusive 12-Bit D/A Converter
Doug Grant 8/15/2013 21 comments
Making a 12-bit DAC is easy on paper, but difficult to do in practice. At least to be really 12-bit accurate and stay that way over time and temperature. Close does not count.
Nanophotonics: Promise for O/E/O Integration
Joshua Israelsohn 8/14/2013 33 comments
The integration of optical and electrical devices on silicon, and the ability to convert from electrical to optical and back, are paramount in the design of high-speed communications channels.
Transistor Packaging: A Thing of the Past?
Alex Lidow 8/9/2013 18 comments
As we pack more functionality into our IC packages, it becomes more difficult to get the heat out. This is especially important when the functionality is RF or power. Here's how it can be done.
Is There Anything Left to Invent or Discover?
Jason Bowden 8/5/2013 17 comments
Is it time to shut down the Patent Office because all the good stuff has been invented? Or are there still plenty of good -- or clever -- or crazy -- ideas floating around, just waiting for the right implementation?
The Diabolical & the X-Ray
Peter Zawistowski 8/2/2013 42 comments
How long does it take to construct a weapon that injures or kills large numbers of people fairly quickly? Probably forever if you're a doofus.
Wires & Power Are the Limiters
Brian Bailey 8/1/2013 16 comments
Typically, to supply power and transmit data, wiring/cabling is used. Anything that can be done to reduce or eliminate the cabling will reduce cost, increase reliability, and generally allow greater intercommunication between devices.
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
