Dynamic Use of the Disable Pin on an Amplifier
Steve Taranovich  
2/28/2018   2 comments
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).

One of the most important parameters of an electric car is the efficiency of the power conversion process, a parameter that measures how efficient is the process of utilization of electric energy in the electrical system, which in turn allows zero-emission driving
Signal Chain Basics #133: Designing summing active filters
Signal Chain Basics

In this article, I’ll 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
High-Efficiency Analog Amplifiers, Part 3: Optimal Parallel-Segmented Voltages
Dennis Feucht  
2/5/2018   Post a comment
Optimal parallel-segment amplifier voltages are derived so that for either resistive or constant-current loads, the power dissipation in the parallel transistors is the same.
Top 10 most helpful engineering books for 2017

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.
