A new report confirms what most of us already knew that data center energy demand is rapidly outpacing supply. And for those who’ve heard of the smart grid so 99% of us) the concurrent issue is no less surprising delivering the electricity ...
How to design a simpler filter (or filter-like circuit) with a varying time constant dependent on what kind of waveform is fed to it. Discussions with some former coworkers have focused on how to design a filter or circuit with filter-like ...
As AI data centers sprout up across the globe, we’ve begun grappling with AI’s not-so-hidden secret it has a voracious, unquenchable appetite for power. Some cities have even passed moratoriums on new AI data centers because of their ...
Butterworth response circuits come in both low- and high-pass versions, as well as ideal, Sallen-Key, emitter follower and DC accurate variants. Many decades ago, I published a Design Idea about using equal value resistors and capacitors to ...
Gray codes, also known as reflected binary codes, offer a clever way to minimize errors when digital signals transition between states. By ensuring that only one bit changes at a time, they simplify hardware design and reduce ambiguity in ...
The frequency response of a Butterworth filter is not supposed to have any peaking. SPICE claims the contrary. I came across an online datasheet for some op-amps where I found two schematics that intrigued me. Screen-shotting them together resulted ...
Abstract This article explains why Bode plots are used to showcase the transfer function of a power supply loop. While there are load transient tests in the time domain, the results do not show other important information that a Bode plot does. ...
Power line communication (PLC) has been around for decades. It’s a foundational technology for smart grids and industrial networks. Yet, despite widespread deployments, it’s still widely misunderstood. As energy infrastructure expands ...
For some time, minicomputers were a dominant force in computing. But where do they stand now? The Electronic Design April 1970, Vol. 18, No. 9. cover article, The minicomputer: machine with an endless future, highlighted minicomputers. They had ...
Before a circuit designer decides on a particular power supply, he or she will first want to test it carefully. The data sheet for a switching regulator IC provides valuable information on how the complete power supply could behave in real life, as ...
