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 […]
by Majeed Ahmad Temperature sensors come in a number of mechanical, electrical and solid-state electronics forms and are widely used in industrial, consumer, medical, automotive and computing segments. Take the case of an engineer who is using an analog temperature sensor—a thermistor—to monitor a fish aquarium – a mature application with a predictable temperature range. […]
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…

by Jon Wilder Most PIC microcontrollers have some form of non-volatile EEPROM on chip. However, the largest I’ve seen is 1KB available on the 18F series. There are many applications in which we may need a great deal more than this. The storage you don’t have For instance, what if we have a MIDI device […]
We straddle two realms, analog and digital. The output of a sensor, musical instrument, the human voice, and most of the signals that originate in the real world are analog. Today most information processing is digital. This works well in terms of audio and video quality, but analog data must be converted by an analog-to-digital converter (ADC) […]
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 […]
