I Still Have a Vacuum Tube in My House?

: The legendary vacuum tube still has an irreplaceable role in mass-market and specialized applications, but that too may be changing due to progress in solid-state devices and designs.
Supergroup Van Halen Was Once Used to Promote PCs

It may come as a shock that PCs were not always common in life and music was once generated through ANALOG technology of vibrating guitar strings altered by pushing pedals, pulling levers, and twisting potentiometers.

The data sheet for the amplifier that I’ve chosen for my application specifies a small signal bandwidth along with a large signal bandwidth, and they are quite different specs. How do I determine if my signal qualifies as small or large?
Diff-Amp Uses a Resistor Network
Dennis Feucht 4/14/2016 2 comments
Low-cost integrated resistor networks can be used to implement a low-parts-count two-op-amp differential amplifier with low common-mode gain. Integrated onto a common substrate and processed together, resistors of integrated networks match well and are an alternative solution to discrete resistors, especially for amplifiers with a wide common-mode input voltage range.

Google has recently joined the Open Compute Project (OCP), and has announced a 48V DC power distribution technology to the rack and then down-converted to 1VDC or less as close to the processor as possible.
PI Continuum Simulation: Load Modulation
Raj Nair 4/7/2016 Post a comment
How do advanced design changes impact power integrity? This is a question often encountered by power-integrity aware IP block designers. And here is where a front-end analysis environment such as Anasim's PI-FP is most useful.
The Benson High-School Electronics Class Rose Festival Prank
Dennis Feucht 4/6/2016 Post a comment
Every year, a big festival is held in Portland, Oregon - the Silicon Forest - that is not quite as famous as the Pasadena Rose Parade, though its parade was carried on network television in the 1960s, when I was in high-school. In the mid-‘60s, Benson Polytechnic High School was rated nationally as number two behind the Bronx School of Science in New York
Kalman or FIR Filter for my IMU?
Ian Beavers 3/30/2016 4 comments
In configuring my Inertial Measurement Unit (IMU) for post-filtering of the data after the sensor, I see options for both a decimation FIR filter and also a Kalman filter. Which one is best for my application?
The Drone Dilemma, Part 6: Drone Racing and Yet Another Acronym-- FPV
Scott Deuty 3/30/2016 3 comments
It’s finally time to have a fun blog on drones. Whereas the first five blogs were more about the restrictions of drones, this blog addresses the fun sport of drone racing. For the most part, we dodge the restrictions. Like anything associated with drones, restrictions are leaking into drone racing
How to use slew-rate control for EMI reduction
Steve Taranovich 3/20/2016 2 comments
Many industrial and automotive applications use the synchronous buck converter power-supply topology; these applications also require low conducted and radiated emissions to ensure that the power supply does not interfere with other equipment sharing the same bus
Not Quite Darwin’s Theory of Evolution
Ken Coffman 3/16/2016 2 comments
It strikes me there is natural evolution happening before our very eyes. What was analog, is becoming digital. For the next step, there are already signs that the digital is becoming software. There’s the well-trodden path: analog becomes digital, digital becomes software.
The Birth and Journey of the Ribbon Microphone
Steve Taranovich 3/13/2016 2 comments
The year was 1924 when Dr. Walter H. Schottky and Erwin Gerlach co-invented the ribbon microphone. The design was made up of a very fine ribbon suspended in a magnetic field that could generate electric signals.
Slideshow: Medical Prostheses Marvels
Steve Taranovich 3/10/2016 Post a comment
Engineering advances in the field of surgical amputation and the art and science/technology of designing artificial limbs have made it possible for persons who have lost a limb to receive a prosthesis that is able to function efficiently while looking like the original.
eGaN Technology Reliability and Physics of Failure
Alex Lidow 3/1/2016 Post a comment
In this first installment and the next, we will look at the field experience from the past six years of GaN transistors use in a variety of applications from vehicle headlamps to medical systems to 4G/LTE telecom systems. Diving into the failure of each and every part leads to some valuable lessons learned.

Being an engineer/journalist and remembering my New York University student days at the Bronx, NY Heights campus from 1968-1972 when I became “socially aware”, I have had many experiences during my life when the choice to do what people, managers and others urged me to do something underhanded, sneaky or convenient and sometimes bordering on criminal, but my conscience and moral compass said otherwise.
Examples of Capacitive PGA/ADC Applications
Field reliability is the ultimate metric that corroborates the quality level of eGaN® FETs and ICs that have been deployed in customer applications.
This blog is about my experiences in a quest for you, the Planet Analog readers, to get your idea patented and pursue your entrepreneurial side.
On July 23, 2015 Kepler discovered the first near-Earth-size planet in the “habitable zone” around a star acting as a sun. This effort helps to find another “Earth” which may inhabit life forms.
