John Gallagher from Pulse Electronics recently spoke with us about some of the things design engineers and circuit designers need to know when they’re working with a company that makes transformers and inductors. He says a lot of circuit designers look at transformers as ideal transformers –there’s just a certain number of turns in the […]
APEC 2019: Up close and personal with a low-profile power supply
Alex Karapetian from Acopian recently sat with us and discussed a new, low-profile switching supply that is a programmable, provides a 450-W output, and sits in a low-profile housing. It’s offered both in single output and wide adjustable from 0 to 5 V, 0 to 135 Vdc, at 150W. It’s also a universal input device. […]
How can you get digital temperature data?
At Sensors Expo 2018, Mike Mays from Analog Devices explains the LTC2983, a temperature to bits IC. The IC is designed to be an extremely easy to use part. Everything necessary to measure temperature is performed by the chip and its output is in direct degrees C. In the display, an “EMI (electromagnetic interference) Hairball […]
How eGaN transistor technology improves Lidar performance
Alex Lidow from EPC recently filmed a video with us covering Lidar, a hot subject right now for autonomous vehicles. One of the biggest applications for eGaN is driving these lasers. The reason is that automakers want to see a long distance with a high degree of accuracy. To do that, the laser in a […]
Graphics-intensive apps get more juice from GaN dc/dc converters
Alex Lidow from EPC recently did a short video with us covering a brand new GaN-based DC-DC converter that’s super small and efficient. Lidow says EPC has been working to improve GaN-based dc/dc conversion for about eight years. They had to overcome a lot of barriers to do so because when they first started, there […]
A DIY vector network analyzer? Yes, there is such a thing
Believe it or not, there’s a do-it-yourself vector network analyzer that can be constructed with a few readily available parts which also can provide measurements accurate enough to be useful in professional work. The basis for the VNA is a chip from Mini-Circuits. Mini-Circuits president Ted Heil explained the ideas behind the DIY VNA in […]
VIDEO: Time Domain Display Items in the Tektronix MDO3000 Series Oscilloscope
Time domain items are in the oscilloscope display are listed with explanations. Hi once more and welcome to our 90th Test and Measurement Video. Today’s topic is the Tektronix MDO3000 Series Oscilloscope, and items that appear in its time domain display. To illustrate, we accessed a ramp waveform from the arbitrary function generator and fed […]
VIDEO: Seed Rivers asks —What do you need to bring your innovation to market?
EEWorlonline editor Aimee Kalnoskas speaks with entrepreneur and president of Master Electronics Jamil Nizam, about how a culture of family and mentorship brought him his new venture, Seed River. Master’s newly-formed investment firm provides the resources needed to help develop and launch products from entrepreneurs, start-ups, and early-stage companies. Just listening? Check out the EE […]
VIDEO: Frequency Menu in the MDO3000 Tektronix Oscilloscope
Bench-type spectrum analyzers are generally more costly than comparable oscilloscopes, but the Tektronix RSA306B makes use of the owner-supplied PC to reduce the cost substantially while maintaining a full range of features and specifications. Greetings once more and welcome to our 89th Test and Measurement Video. Today’s topic is the Frequency Menu in the Tektronix […]
Video: How Gallium Nitride semiconductors will make your home and workspace completely wireless
Wireless power is ready to take its next big step forward. Imagine sitting at work with your monitors, phone, and computer at your desk while not having to worry about a single power cable. That’s the future thanks to semiconductors. Gallium Nitride power semiconductors could make it possible to transmit power wirelessly to […]
