Electronic engines valves: an idea whose time has come … and gone?, Part 1: conventional engine design
The electronically controlled, cam-free internal combustion engine seemed like a good idea, but technical and market realities stifled its acceptance. Despite all the attention given to electric vehicles (EVs) as the inevitable replacement for vehicles powered by the venerable internal combustion engine (ICE), the reality is that for the foreseeable future, cars and trucks will […]
What is a Bode plot?
A Bode plot represents the gain and phase of a feedback system as a function of frequency. It was developed by Hendrik Wade Bode in the 1930s and reflects the system’s frequency-domain behavior. He invented it while at Bell Labs to help design stable amplifiers with the feedback needed in telephone networks. The graphical design […]
AC challenges with inductors
To get good performance from inductors in power supplies, you need to be careful about the AC characteristics. Physical inductors are complex structures, not ideal components. And the AC challenges with inductors are growing due to the higher operating frequencies of power supplies using silicon carbide (SiC) and gallium nitride (GaN) power switches. This FAQ […]
How it works: Base station on a chip
EdgeQ is sampling what it calls a “base station on a chip” that handles high-PHY through baseband
Introduction to Raspberry Pi 4
Raspberry Pi is a credit-card-sized, single-board computer developed by the Raspberry Pi Foundation, a UK-based charity that works to ensure global access to computing and digital technology. It was initially developed as a low-cost microcomputer to impart digital skills to kids. It comes without any power supply or peripherals as it’s meant to be programmed […]
Teardown: D7 robot vacuum from Neato Robotics
The D7 robot vacuum from Neato Robotics in California boasts a lot of navigational features such as zone cleaning, no-go lines, and floor plan mapping. We tore down a D7 to see how these features are implemented and to get a close look at the lidar unit that helps the bot find its way around. […]
DC voltages, AC voltages and Stiff voltages
At its most basic level, voltage is a simple concept. Voltage, also referred to as electric potential difference or electromotive force (emf), is the difference in electric potential between two points. In the International System of Units (SI), one Volt equals one Joule of work per Coulomb of charge. In practical applications, voltage is simple, […]
The practical magical first-order analog filter: Part 1
Finding the right analog filter to build a sensor circuit doesn’t have to be complicated. Understandably, the plethora of filter options can be overwhelming. Also, selecting a less-than-ideal filter may result in compromises, potentially increasing system cost, or affecting performance. To help simplify filter selection, this series of blogs explore key considerations when assessing your […]
EM simulation is crucial to 5G wireless design
5G Technology World spoke with Jonathan Oakley of Dassault Systemes on how the company’s electromagnetic simulation software helps engineers design and evaluate antennas for smartphones and IoT devices.
