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)
At the heart of a transceiver is usually a phase-locked-loop (PLL) synthesizer, which delivers a signal to downstream components such as mixers, filters and power amplifiers.
The steps we will look closely at are the fine leak and gross leak seal tests, external visual, and radiation latch-up tests
Recently, AEye, was demonstrating their LiDAR system at CES in Las Vegas. A man using his new $1,198 Sony camera found that his photographs were damaged after he took pictures of AEye’s LiDAR LASER scanning system
The e-car basic concept is represented by the role of the electronics technology in making the car more comfortable, safe and effectively interacting with the driver. The first characteristic, comfort, is nowadays being dramatically enhanced by the new solution known as Road Noise Control (acronym: RNC) that has been introduced by BOSE during the CES 2019 in Las Vegas
Early microcontrollers had fixed I/O. It may have been possible to connect one of several internal peripherals to the I/O pins, but those pins were restricted and there was never an option of conditioning those outputs
