How to Regulate a Power Supply from a Wide Voltage Range
Xiuge Yang  
5/24/2019   Post a comment
This article discusses how using a single synchronous buck controller can output the most common voltage rails, and accommodate a wide range of operating input voltages from 3V to 40V, and at a reasonable BOM cost.
SiC switches in electric vehicles - will they dominate the drivetrain?
Dr. Anup Bhalla  
5/22/2019   Post a comment

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.

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.
Stability Issues and Resolutions for High Speed Fully Differential Amplifiers (FDAs), Insight #8
The Signal Sped Up  
5/1/2019   2 comments
The most recent VFA FDAs focus on lower power, precision, solutions more aimed at Successive Approximation Register (SAR) and delta sigma ADC support. Those will be focus in this FDA stability discussion - but the concepts are backward compatible to the earliest VFA FDAs.

11 things you need to know about resistors in pulse load applications
Annika Elsen  
4/24/2019   2 comments
It’s an unfortunate fact that a resistor can fail under pulse loads. When pulse power is dissipated to the device’s resistive element, it generates heat and increases the resistor’s temperature.

Frederik Dostal  
4/22/2019   Post a comment
In such things as laboratory power supplies or electronic systems, in which various components are connected to longer cables, the regulated voltage is not always particularly accurate at the point where it is needed due to various voltage drops across the interconnection lines.

Wishful Thinking
Aubrey Kagan  
4/17/2019   1 comment

As we deal with the vagaries of life and work, occasionally we come up with an idea to improve the process. If the idea is big enough or the inventor has entrepreneurial leanings there may be an attempt to commercialise the product/process. Sometimes pie-in-the-sky ideas seem too small and are left in a corner of the mind, only to reappear as someone else’s brilliant idea.

Now, our customer doesn’t want to buy big, expensive, high quality capacitors to build an active filter with this response. So, having established the principle of optimizing in the analogue domain, let’s look at whether need to make any changes in order to use it to create a digital filter – which we’ll be able to implement on the Cypress PSoC 3
