In this first column of 2018, the publisher of ASPENCORE reflects on our journey the last three years and glimpses ASPENCORE’s future
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
Rauch filter basics
Steve Taranovich 1/28/2018 Post a comment
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
Steve Taranovich 1/14/2018 3 comments
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.

I will be publishing a series of tutorials regarding Analog Mechatronics on Planet Analog over the next few months.
The Father of Massive MIMO
Steve Taranovich 1/2/2018 Post a comment
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)
A Quick Overview of Radiation Effects
Jonathan Harris 12/21/2017 Post a comment
While brainstorming on topics to write about this month it occurred to me to combine the two areas in which I’ve worked and talk a bit about a few types of radiation effects on high speed ADCs.
Recently, an amateur astronomer, Scott Tilley in Roberts Creek, British Columbia, amazingly found NASA’s IMAGE spacecraft more than 12 years after it went dark.
Electronics technology is contributing heavily to the automotive industry with ICs for the DC-DC conversion utilized in the creation of voltages suitable for the central processor to enable actuators and to process the signals coming from the electronic sensors.
The additional connection between numbers and the physical world is achieved through the use of units
Antennas have come a very long way from the classic metal-element versions; are you ready for their next phases?
