Industry heavyweights and aspiring startups alike are developing semiconductor integrated circuits (ICs) to ... Filter Design using the “Million Monkeys Method” Kendall Castor-Perry, Filter Wizard extraordinaire, 5/18/2019 Comment now Previously here on The Filter Wizard we saw how to use a spreadsheet such as Excel to calculate the frequency response of a filter network with a ladder form in Simulate Circuits in a Spreadsheet with some 'Ladderal Thinking'. This form covers a wide range of common filter circuits, from loudspeaker crossover networks through to high performance ... MOSFETs embedded into PC boards Steve Taranovich, Editor-in-Chief, Planet Analog, 5/18/2019 Comment now 1 Comment Schweizer will embed power MOSFETs directly in a PCB instead of mounted on the board exterior. The thermal benefits of this innovation enable higher power density that is ideal for 48V automotive power systems in Mild Hybrid cars (Courtesy of NY Daily News).

Simulate Circuits in a Spreadsheet with some ‘Ladderal Thinking’ Kendall Castor-Perry, Filter Wizard extraordinaire, 5/18/2019 Comment now 1 Comment So, filter fans, I hope you tried out my recent spreadsheet-modified simulation schematic method Excel Tunes Up your Schematic Files. It's a nice way of creating small circuit chunks with calculated component values, especially when the sums can't be carried out using the math capabilities of your simulator's preprocessor.

Aircraft: Angle of Attack (A0A) Sensor design Steve Taranovich, Editor-in-Chief, Planet Analog, 5/15/2019 Comment now 15 comments As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design. I always say, "Follow the money" and you will likely find the cause of most problems. Whether it is a rush to get a product to market before your competitors, or an effort to make more money on product options, ... Most recent post, MWagner_MA, 5/22/2019 9:00:01 AM While not an expert in reliability engineering, I have had some training in it as... GaN transistors address data center and telecom server power requirements Dr. Gerald Deboy, Senior Principal Power Semiconductors and System Engineering, Infineon Technologies, 5/12/2019 Comment now The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices. When the system is ... Flyback Converters Without Optocouplers: Existing Options Frederik Dostal, Power management technical expert, Analog Devices, 5/10/2019 Comment now Editor's note: There is a great deal written about isolation, but Frederik Dostal gives us a look at power supply isolation. Do you know which side of the galvanic isolation to put the controller? Should you use optocouplers or some other method? Find out here. Excel Tunes Up your Schematic Files Kendall Castor-Perry, Filter Wizard extraordinaire, 5/9/2019 Comment now 2 comments In previous posts I've talked about transferring spreadsheet-based circuit design "directly" to the lovely LTspice simulator, and a reader of The Filter Wizard was keen to understand exactly what "directly" actually meant, and to get some practical information on how to do it. Most recent post, TucsonMike, 5/15/2019 8:54:53 AM Hey Kendall, Very nice article and useful linking of LTSpice to Excel.... Discrete Difference Amplifier vs. an Integrated Solution Steve Taranovich, Editor-in-Chief, Planet Analog, 5/9/2019 Comment now Question: Why Pay More for Less? Automating Analog Layout Keith Sabine, Product Manager, Pulsic, 5/8/2019 Comment now There has been vast progress over the last 30 years or so in digital layout automation, which has made it possible to develop complex digital ICs relatively quickly. However, for analog layout, techniques are still much the same as they were years ago. True, there have been some improvements such as using parameterized cells to generate Design Rule Check ... Robots re-charge their own batteries Steve Taranovich, Editor-in-Chief, Planet Analog, 5/7/2019 Comment now The future is here---Autonomous robot and drone usage is growing quickly, especially in Industry 4.0 ---the Fourth Industrial Revolution.

I believe that having two different sensors would be even more reliable, but I am not completely... steve.taranovich on Aircraft: Angle of Attack (A0A) Sensor design 5/21/2019 5:33:09 PM Re: L-1011 AOA Sensor: There are dozens of different AOA sensor designs used on different aircraft -- my thinking is with two pairs of two different sensors one would not have all affected in an incident BillWM on Aircraft: Angle of Attack (A0A) Sensor design 5/21/2019 5:00:53 PM Re: L-1011 AOA Sensor: @BillWM----That L-1011 sensor looks to be much better protected against 'bird strikes' and possible taxi damage during arrival and departure at the gate steve.taranovich on Aircraft: Angle of Attack (A0A) Sensor design 5/21/2019 4:40:13 PM L-1011 AOA Sensor: https://aviation.stackexchange.com/questions/61168/what-were-the-advantages-of-the-l-1011-aoa-sensor-design BillWM on Aircraft: Angle of Attack (A0A) Sensor design 5/21/2019 3:57:26 PM Re: Maybe what would be best is redundant dissimilar AOA sensing methods for each sensor: The real issue is in the air transport industry most of the prime and sub contractors have been "leaned out to the point of detonation" and the corporate budgets for R&D reduced -- This is one of those things that would save airlines money... BillWM on Aircraft: Angle of Attack (A0A) Sensor design 5/21/2019 3:49:10 PM Re: Maybe what would be best is redundant dissimilar AOA sensing methods for each sensor: @BillWM---Nowadays, due to budget constraints, NASA is working with private contractors like SpaceX, Blue Origin, and more. Why can't the FAA work with private contractors for something like this? steve.taranovich on Aircraft: Angle of Attack (A0A) Sensor design 5/21/2019 3:44:05 PM Re: Maybe what would be best is redundant dissimilar AOA sensing methods for each sensor: The one issue with the MEMS sensor that comes to mind is for a wing like an airliner wing with all the lift augmentation surfaces deployed in the high lift mode the required acuracy for the AOA sensor aproaches 0.1 Deg or less.
