Filter Design using the "Million Monkeys Method"
The Filter Wizard Remastered 5/18/2019 Post a comment
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.
GaN transistors address data center and telecom server power requirements
Dr. Gerald Deboy 5/12/2019 Post a comment
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.

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.
Automating Analog Layout
Keith Sabine 5/8/2019 Post a comment
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.
Improving a robot controller: Replacing tanh(x) with sin(arctan(x))
Steve Taranovich 5/6/2019 2 comments
Most of us probably have never used the hyperbolic tangent function tanh(x) or the sin(arctan(x)) reference function since our university days. But these functions enable a kinematic controller. Kinematics determines the position and orientation movement of an end-effector on a robotic arm as a function of the joint coordinates.
The utilization of electronics in medical applications could effectively enhance the quality of life of patients and prevent many cardiovascular distresses: this is confirmed by the result of an observational study, about the CPAP device
This blog series deals with the potential of the utilization of smart electronic ICs in medical care applications; these ICs are produced by companies in the field of semiconductors such as STMicroelectronics which has a broad portfolio of ICs for medical applications
There is rising interest in alternative energy schemes and electric vehicles (EVs) which means there is a growing need in making it possible for power to flow efficiently in both directions.
The industries sector is progressively increasing utilization of IoT technology to make the industrial processes automated in a very intelligent way.
Medical care applications with electronic devices are becoming progressively more important and massively adopted.
