Mechatronics: Power Amplifiers
Steve Taranovich  
3/28/2018   1 comment
Power amplifiers/drivers are important in Mechatronics because they are the ‘Movers and the Shakers’, so-to-speak, in Robotics and other Mechatronics applications.
Multifunction Microprocessor Control and Regulation of Power

Deciding which power-device driver to use may not seem like a big deal, but how well it matches the power device and design objectives is an important factor in overall performance and reliability.
Output offset calculations in Op Amp-based circuits
Rajesh Pathak  
3/21/2018   Post a comment
In this article, a generalized method is proposed to compute offset in the output when an Op Amp with an input offset e is used in the circuit.
Mixed-Signal Circuits, Part 2: ADC and DAC Dynamics, the w-Domain, and Feedback Loop Design
Dennis Feucht  
3/19/2018   Post a comment
In this part, we push forth to transfer functions in s and z of ADCs and DACs, then consider briefly how to design feedback loops that span the analog-digital boundary.

As vehicles become more electrified, it becomes more critical to accurately monitor the current in many subsystems to ensure performance as well as long-term reliability.
Still another hidden 'Gem' from APEC 2018: AEM, Inc.

3/16/2018   Post a comment
AEM, Inc. did have a small booth at APEC 2018 this year and I had the pleasure of meeting Jeff Montgomery, General Manager, AEM. High-Rel fuses and tin whiskers were our topics of discussion. Both of these topics are frequently after-thoughts by circuit designers.

My top hidden 'Gems' at APEC 2018: Renesas/Intersil
Steve Taranovich  
3/12/2018   1 comment
While at APEC 2018 last week in San Antonio, TX, there were a great many excellent new offerings and developments for the power electronics industry. Sometimes, what some may consider lesser displays and discussions, can get lost in the shuffle at such an event, so I wanted to highlight some of these ‘Gems’ that I noticed while roaming the exhibit floor and seminar rooms.

Is placing a 100 ohm resistor in front of a MOSFET gate required for stability?
Mixed-Signal Circuits, Part 1: From s to z - The Discrete Complex-Frequency Domain

This article series is a mini-tutorial on the discrete complex-frequency domain and its complex variable denoted as z
Can you charge your EV faster?

There have been many announcements about rollouts of electric vehicles (EVs) across the globe.
APEC2018: EPC Professional Education GaN Seminar
Steve Taranovich  
3/5/2018   2 comments
Alex Lidow and his team of Michael de Rooij, David Reusch, and John Glaser gave an excellent technical tutorial this morning to a packed audience of Professional Engineers (PEs).
Digital Temperature Sensing with the Aid of LTspice
Alain Stas  
3/3/2018   Post a comment
Before you start building a digital temperature sensing circuit, you must take the pure mechanical aspects (not treated in this article) and the electro-thermal aspects of your design into account. To that end, there are several important questions to consider.
Choosing and Using GaN Technology for High-Efficiency Power Conversion
Rudy Ramos  
3/3/2018   Post a comment
The goal to increase energy efficiency and reliability, while reducing overall solution size, is prevalent in modern power-electronics applications.
Choosing the optimal LPDDR4 power supply
Chris Glaser  
3/1/2018   Post a comment
In this article, I’ll compare three Texas Instruments (TI) power solutions for LPDDR4 portable applications, comparing their output-voltage accuracy, efficiency and solution size to obtain an optimal solution for a wide variety of applications.

There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
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
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.
