Simple Transient-Response Measurement Determines Power-Supply Bandwidth
01.11.2018 · Articles
It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response – no good reference exists that defines this in simple terms. It seems like a straightforward problem, which should have a simple solution. The higher the bandwidth, the faster the loop responds, and with less voltage deviation...
Synthesized Inductor Delivers Maximum Power Transfer
12.28.2017 · Articles
To transfer maximum power from a circuit to a load, the load’s resistance, RL, must match the source resistance, RO. In the case of a complex load, ZL, and a resistive source, this transfer can require the use of a bulky inductor. This idea shows how to replace the physical inductor with a smaller synthesized inductor...
10 Best Raspberry Pi and Pi 2 Alternatives. Part 2
There are actually two versions of the MinnowBoard MAX available; a $140 version and a $100 version. The extra $40 gets you 2 GB of RAM instead of 1 GB, but both versions include a 1.33 GHz dual-core processor...
10 Best Raspberry Pi and Pi 2 Alternatives. Part 1
The Raspberry Pi and Pi 2 have taken the world by storm and created a huge interest in single-board computers; their simplicity, portability, and affordability make them great for thinkerers and kids alike. But not everyone wants a Pi...
Generate A Differential Signal Using A Transformer Plus Signal Splitter
12.06.2017 · Articles
Most function generators and network analyzers have one port to provide the output signal. If a differential signal is needed, then you may need to acquire a network analyzer with two output ports at great cost. Of course, there are alternate solutions in generating a differential signal without acquiring expensive equipment...

Simple trick lets you see your parts
11.13.2017 · Articles
All too often, we electrical engineers are under the gun to get a circuit working now, and don’t have the luxury of ordering parts and waiting – even a day. The problem: loose parts in the tool box can be nearly impossible to read – even under bright light and high magnification...
