IMS2015 – Day 3: The Final and Shortest Day Jonathan Harris 5/22/2015 Post a comment The last and final day of the show is usually has the most relaxed atmosphere and this year that proved to be the case once again. It is the shortest day of the show lasting from just 9:00 AM to 3:00 PM.
IMS2015 – Day 2: The Long Day Jonathan Harris 5/21/2015 1 comment After having a pretty good first day of the show, I was looking forward to a good second day and it did not disappoint. The second day of the show on Wednesday is the longest day of the show as the exhibit hours go from 9:00 AM until 6:00 PM (day one is 9:00 AM to 5:00 PM and day three is 9:00 AM to 3:00 PM).
IMS2015 – Pre-Show: The Preparation Jonathan Harris 5/18/2015 Post a comment It sure doesn’t seem like it has already been a year since IMS2014! Well, technically, it hasn’t been since IMS2014 was in June last year. Once again this year IMS (International Microwave Symposium) is in a state known for its sunshine albeit this time sans the humidity. This year the show visits sunny Phoenix, Arizona.
The STEM of all Evil, Part 2 Ken Coffman 5/11/2015 7 comments Let’s teach the students about the strengths and limitations of real components, then add mathematical formulas on top later and only in terms of what is known about real components and real designs.
Using Deep N Wells in Analog Design Keith Sabine 5/7/2015 2 comments On a conventional CMOS process, NMOS devices are formed in a P well or substrate connected to ground (or the most negative supply in the circuit). PMOS devices are formed in an N well connected to the most positive supply
MOSFETs Balancing High Value Supercapacitors Greater Than 1000 Farads Robert L. Chao 4/28/2015 1 comment We have frequent input from our customers who are developing supercapacitor modules consisting of two or more cells stacked in series and who want to know how to utilize MOSFETs to balance leakage current. Several engineers had a misconception and dismissed low current MOSFETs because the charge and discharge current of the supercapacitor exceeded that of the MOSFET.
Six Cool Android Apps For Analog EEs Paul Pickering 4/23/2015 4 comments With Android continuing to make inroads across the board (64% market share in tablets and 53% in smartphones as of Q1 2015), it's time to take a look at some cool Android apps for analog EEs.
Let’s Not Forget the Mars Opportunity Rover Steve Taranovich 4/22/2015 2 comments Most of us know about the latest Rover to land on the Red planet called Mars—Curiosity. But did you know that since January 2004 NASA’s Mars Rover called Opportunity has traversed the Martian landscape a distance of 26.661 miles, just a little more than the distance of a full marathon run.
The GaN Era Approaches Tim Kaske 4/14/2015 4 comments Gallium nitride (GaN) is now coming to the fore, possessing many characteristics that will allow production of power transistors which outperform Si devices
Moore’s Law Demise: Maybe It’s a Good Thing! Steve Taranovich 4/11/2015 6 comments Moore’s Law will celebrate its 50th anniversary on April 19, 2015. Many say that the statement or theory has run its course due to the next moves toward 450 mm size wafers, extreme ultraviolet lithography (EUV) and 20 nm CMOS.
When Blueprints Were Really Blue: Is Engineering Becoming Less Satisfying? Paul Pickering 4/8/2015 10 comments I graduated college in 1979 (yeah, I know.... makes me about 35, right?). Back then our college Comp Sci department had less processing power than a modern toaster. There was talk, probably apocryphal, of a PDP-11 somewhere in the building, but we in the Physics department cut our teeth on a PDP-8, which had less processing power than a modern slice of toast. Nonetheless, we made do, learning machine code, assembly language and FORTRAN, booting up the machine with a strip of paper tape and entering our programs via punched cards.
EMI Noise, Part 4: Box Level EMI Suppression Edgardo Menendez 4/7/2015 1 comment So far, we have discussed board level EMI suppression solutions, which are necessary to meet EMC standards. However, they may not be sufficient for applications in which the enclosed system is either not immune to, or even emits, EMI. Applications like these — including medical, space, aerospace, and other mission critical systems — require box level EMI filtering
Can μCs Replace Analog Circuits? Dennis Feucht 4/7/2015 8 comments The cult of DSPism believes that eventually there will be essentially no analog circuits, that all circuitry will be either digital, as microcontrollers (μCs), with mixed-technology ADCs and DACs. This article explores the possibilities and limitations on this viewpoint
Logic Ken Coffman 4/2/2015 Post a comment Here’s something annoying about engineers and anarcho-reductive philosophers—our training and background in Boolean logic. We tend to be analytical, even when making routine decisions—like what to have for dinner.
ADC Input Resistance: A Question of Sampling Kendall Castor-Perry 4/1/2015 Post a comment One of our field applications guys wanted to know the input resistance of one of our ADCs; a customer had asked him and couldn’t find the data. Like most integrated ADCs these days, this one (the SAR ADC in our PSoC 4 family of devices) has a switched-capacitor front end and, in the interests of maximum flexibility and minimum power consumption, we don’t fit an input buffer amplifier. We let you do that if you want, but sometimes people want to ‘go native’ and feed the ADC directly.
Make a Freezer Alarm Using a Power Op Amp with Zero Power Consumption Steve Taranovich 3/31/2015 6 comments When your home’s deep freezer, full of food, experiences an AC power failure while you are out for an extended time, its contents can thaw out. If the AC power is then restored before you return home, the contents can re-freeze and you may never know that your food is spoiled. This has given rise over the years to a number of freezer-alarm circuits and methods to detect thaw and re-freeze.
5G: Where Are We Now? Steve Taranovich 3/31/2015 Post a comment It seems like we just had LTE and LTE Advanced beginning deployment in base stations everywhere. In spite of that effort, there has been heavy discussion of early development ideas of the 5G next-gen architecture to meet the ever-growing demands of the cellular airwave capacity, speed and customer future needs.
When Developing New Silicon IP, Is First Pass Success Possible? Part 1 Brandt Braswell 3/31/2015 Post a comment If you have worked in the semiconductor industry for more than a few years I am sure you have heard senior leadership speak about the need for your integrated circuit designs to be first pass successes and not the typical two to three spins or more to reach the targeted performance. The question is this: Is first pass success feasible and should be expected? I do not want to stir up a hornets nest with my response but the answer to the question is that it depends. Depends on what you say? Well, the answer depends on several different interwoven complexities that can determine if first pass success is possible. I would like to explore some possible ways to answer this question. Furthermore, the complexity of this question increases when developing complex mixed signal IC’s.
Don't “Brick” My Supply! Steve Taranovich 3/20/2015 Post a comment In today’s connected world, software frequent-field updates are necessary to improve accuracy, or add on benefits or even fix bugs. If you like these updates to be invisible to you, you are going to love this idea - Instant updates that do not require your software to restart or cause any glitch in the power supply.
