I discussed the problem of level shifting logic signals a while ago but I noticed the recently introduced NXP AXP level shifters so thought it was worth revisiting the subject to see if these new devices will really help solving the problem of interfacing the increasingly varied power supply voltages in digital and mixed-signal circuits. […]
Accelerometers used to be expensive devices used in aircraft and missiles but now they are very cheap devices found everywhere – for example in your mobile phone. Their use in a mobile phone is not as critical as part of an aircraft navigation system and the accuracy and cost reflect that, with 3 axis devices […]
I recently came across an interesting article by Analog Devices in their February “Analog Dialogue” called “Ferrite Beads Demystified”. It was interesting beyond its analysis of ferrite beads because it covered one of the issues I have seen in the past with regards to power supply filtering — that of resonance between a power supply […]
More and more wind and solar installations are incorporating battery banks as a means of letting the wind or solar generators maintain a level output to the grid…

While a lot of manufacturers have “design” tools to help you choose their parts, there are also other useful tools out there. Some, like Appcad, were just tools without trying too hard to sell you anything. Appcad is still available www.hp.woodshot.com and the current version 4.0.0 is really version 3.0.2 with the branding changed. I […]
While we are all probably familiar with the concept of capacitors storing charge, remember that semiconductors do so as well. This may not be an issue for your design or it could be a major headache, depending on the application. With bipolar transistors, charge storage in the base when the transistor is saturated will slow […]
Choosing an opamp for a particular task can sometimes be simple but at other times, you will have a lot of conflicting requirements which makes choosing more of a challenge. Also, the number of opamps available now is huge so it can take a while to work your way through the options from different manufacturers. […]
Education for electronics design tends to have a fair amount of math in it but how much is really required nowadays in order to design electronics? You certainly…

If you are from a software background coming into digital design using CPLD/FPGAs (complex programmable logic devices/field programmable gate arrays) then you need to adopt a different way of thinking for designing logic. While Verilog and VHDL look like a conventional programming language, the way it is interpreted is different. With software for a microprocessor […]
Telehealth is becoming a new way of helping people achieve a better quality of life, but the proliferation of wireless technologies has also introduced a personal health and medical device interoperability challenge that has not been seen before. The challenge rests in the need to have several wirelessly equipped devices and end equipments communicate adequately […]
