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 ...
Obtain tighter stop band impedance variance via the techniques detailed in this tutorial. Input impedances presented by lowpass and highpass filters in their respective stop bands are usually not controlled and can vary quite widely. Sometimes ...
