Mechatronics: Power Amplifiers
Steve Taranovich 3/28/2018 Post a comment
Power amplifiers/drivers are important in Mechatronics because they are the ĎMovers and the Shakersí, so-to-speak, in Robotics and other Mechatronics applications.
Gate Drivers Get Some Deserved Attention
Analog Angle 3/22/2018 Post a comment
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.
Still another hidden 'Gem' from APEC 2018: AEM, Inc.
Steve Taranovich 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 Post a 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 ĎGemsí that I noticed while roaming the exhibit floor and seminar rooms.
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 the optimal LPDDR4 power supply
Chris Glaser 3/1/2018 Post a comment
In this article, Iíll 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.
Dynamic Use of the Disable Pin on an Amplifier
Steve Taranovich 2/28/2018 1 comment
Some operational amplifiers have disable pins and when used correctly, they can yield up to 99% power savings without compromising accuracy. The disable pin is primarily used in static operation (standby mode).
Signal Chain Basics #133: Designing summing active filters
Signal Chain Basics 2/22/2018 1 comment
In this article, Iíll describe a few easy steps that will convert any Sallen-Key (SK) or multiple feedback (MFB) active filter from a single-input filter to a summing active filter that gives the same response without difficult calculations or analysis

Low Side RDS(on) Current Sensing
Jerry Steele 2/5/2018 Post a comment
Motor drive applications with totem pole outputs often only need to sense current in the low side switch(es) of their phase(s). Including a shunt and an amplifier is a simple and obvious solution, and is really preferred if high accuracy is the objective
On the frontier of electric transport, there is a possible solution with an electric bus fleet adopted in the cities of Luxembourg starting from June 2017 in collaboration with Volvo.
Now letís move to our next SEE topic which is single event transients (SETs)
NASAís Transiting Exoplanet Survey Satellite (TESS) may possibly launch on Wednesday April 18, 2018 this week.
