Rauch filter basics

This is a multiple-feedback (MFB) filter architecture in which there is less sensitivity to component variations than many other filter architectures
Draining Data Center power: Bitcoin mining
Steve Taranovich 1/23/2018 Post a comment
In the virtual currency realm, creating a new Bitcoin will require a great amount of power to be drawn from the power supplies in the data/server racks filled with power-hungry processors turning energy into “gold”
It's time to advance your clock
Graham Mostyn 1/21/2018 Post a comment
The advent of smart, connected appliances has created higher demands on clock performance. This article explains how the designer can meet these challenges while reducing technical risk, design time and bill of materials. We look at the options of quartz crystals, quartz crystal oscillators (XOs) and highly-integrated clock solutions using quartz and MEMS-based technology

In the tradition of Application Engineering greats such as the late Jim Williams, I have a lab at home that I have equipped to do credible testing which results in a document that contains test equipment info, test schematics, and test results.
I2C switches: a closer look
Signal Chain Basics 1/16/2018 Post a comment
Despite this reputation, I2C does have its challenges: a limited number of bits for a unique address can create address conflicts, or multiple devices may require different input voltages. Although solving these problems may seem straightforward, there are implication challenges to consider
Robotics for future young engineers

As engineers, we all need to be introducing youngsters of all ages to the excitement and challenges in engineering. One of the most exciting areas for the young, budding engineer is Robotics.
The Mobile Revolution
Gene Sheridan 1/8/2018 Post a comment
Mobile devices have seen amazing improvements in the last 2-3 decades. Smartphones now have more than 2.5x the computing power of a 1985 Cray-2 supercomputer.

Marzetta’s revolutionary work on antenna arrays began as an academic idea, it is now one of the hottest topics in wireless and will be a cornerstone of next-generation mobile technology
Signal Chain Basics #131: RF-sampling DACs for multiband transmitters
Signal Chain Basics 1/2/2018 Post a comment
High-speed data converters now digitize or generate signals directly at radio frequencies up to several gigahertz, replacing traditional radio-frequency (RF) components like mixers, local oscillators (LOs) and amplifiers. This article focuses on the transmitter (downlink) using an RF sampling digital-to-analog converter (DAC); my next article will cover the receiver (uplink)
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
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.
